HINTS FOR THE OPERATING SYSTEM INSTALLATION
The following chapter should provide support for the installation of the operating system. It is not to be regarded as a complete guide for the installation of the operating system, but provides a few important hints in order to set up the operating system correctly for 250 SCALA.
2.1
SUPPORTED OPERATING SYSTEMS AND OFFICE VERSIONS
Overview tables with the operating systems and Microsoft Office versions supported by each 250 SCALA version can be found in the document "Operating Systems and Microsoft Office Compatibility Sheet". To be found • in the 250 SCALA Help in the section "Installation" or • in the ISI-Web under ISI Item Number D74-143.
2.2
OPERATING SYSTEM INSTALLATION FOR COMPUTERS PRE-INSTALLED BY DELL
The installation of the operating system on "pre-installed" PCs that are supplied by Dell corresponds to the greatest possible extend to that of PCs without a pre-installed operating system (see chapter 2.3, "Operating system installation for computers not pre-installed"). The only difference is merely that on a pre-installed PC from Dell the installation media for the operating system is already available on the hard disk while on a PC without pre-installation the Windows DVD with the operating system has to be present and to be inserted in the DVD-drive.

WINDOWS EXPLORER
The following option must be activated in Windows Explorer: "File name extension"
2.5
INTERNET BROWSER
Internet Explorer has to be installed. To display the webpages of the HTTP-Server the browser Chrome is recommended.

PARTITIONING
With the following partitioning, it has to do with recommendations that have been prepared in cooperation with the ANDRITZ HYDRO Hardware-, Product- and Development sectors. Each project can determine the ideal partitioning for itself, but care must be taken that there is sufficient free hard-disk storage space available on each drive after the installation. As file system NTFS is required. Drive

NETWORK
Each 250 SCALA control centre system has at least one physical network. Thereby it normally has to do with an Ethernet network. This Ethernet network is used for combining the distributed systems (Process computer components, Visualization components) and is also normally used for coupling the automation system to the control centre system. For each 250 SCALA control centre system • a project name or a project abbreviation • a network address (Class-C) is unambiguously determined world-wide by ANDRITZ HYDRO Vienna.
For 250 SCALA projects, so-called free or private network addresses are assigned by ANDRITZ HYDRO as network addresses in the range of 172.16.1.0 to 172.20.253.0. According to a definition (RFC 1918) these network addresses are not used in the Internet. An important reason is to be seen in the possibility of world-wide remote maintenance of 250 SCALA control centre systems with TCP/IP via public networks. Furthermore, as standard the project abbreviation is used to form the Host name and the network addresses are used for forming the IP-addresses. Naturally, Host names and IP-addresses assigned by the user can still also be taken into account. For details see chapter 15.6, "Suggestion for network addressing, network mask and host name assignment".

WINDOWS-USER
It is strongly recommended to create further Windows-Users besides the User "LocalAdmin", that should not have administrator-rights for the operation of 250 SCALA. To operate 250 SCALA, the user has to be a member of the group "Users", only for the FDA Editor ("LogiCAD") he has to be a member of the group "Power Users". The following table is to be regarded as a suggestion for the Windows-User-Definition. An optional number of (additional) Windows-Users can be assigned with optional authorizations and passwords as required. Username

User
User for operation of 250 SCALA
For security reasons, we recommended that a separate administrator password is used for each PC. A user with administrator-authorization is for example necessary for the following operations: • • • • •
Installation Deinstallation Update Repair Add / Remove Components
It is strongly recommended to change the user after finishing the installation. A control center system never should be operated as an administrator or with a user with administrator rights! An incorrect operation made in the administrator mode can lead to fatal effects on the total system.

2.10 MICROSOFT OFFICE MS-Office 2010 must be installed in order to use Excel-Reports or the archive editor. All of the Office editions listed in chapter Error! Reference source not found., "Error! Reference so urce not found." are supported - but only the 32-Bit versions. Microsoft Office must be installed before installing 250 SCALA.
2.11 OPERATING SYSTEM UPDATES It may be necessary to perform an update for individual operating system components if the requirements for the new version of 250 SCALA have changed compared with requirements for the old (currently installed) version. The update procedure checks the requirements and outputs signals accordingly if any of the requirements for the new version of 250 SCALA have not been met. Changes to requirements for the operating system may include: • A more recent service pack • A more recent version of Internet Explorer N.B.: As part of an update of 250 SCALA, individual dll files may be updated too. The next time Microsoft Office programs are started up, the MS Office Installer may become active and an Office update may be requested. These Office applications cannot be used until this happens. It is therefore necessary to have the appropriate Office CD for the relevant project to hand.

The installation of 250 SCALA is thereby successfully completed. The PC now has to be rebooted.
An installation of the TOOLBOX II with CAEXplus and FDA Editor (logiCAD) for 250 SCALA on the same computer is not possible! It can only either the one or the other be installed. An installation of both applications on the same computer results with high probability into a fail of the installation and can make a new installation of the PC necessary. Attention: At the installation of FDA Editor (logiCAD) it is checked if there is already CAEXplus installed (if so, the installation will be cancelled). On the other side the TOOLBOX II at the installation of CAEXplus does not check whether FDA Editor (logiCAD) has already been installed. If FDA Editor is being used, first install the software and only afterwards connect the USB dongle.
In the event that any prerequisite for installation of the individual components is not met, a message indicating this will be displayed.

INITIAL START OF 250 SCALA
If you have successfully concluded the installation of 250 SCALA, then the components that have been selected under "Startup" in the 250 SCALA settings start automatically. These components normally disappear after a short time from the Taskbar, because they are also activated under "Hide". Then start the other 250 SCALA components in the sequence specified.
3.3.1
INITIAL START OF THE SCADA-SERVER
Start the SCADA-Server via the Windows-Start-Menu START | PROGRAMS | 250 SCALA | SCADA SERVER. In the window that appears you will see the individual steps of the SCADA-Server startup. This can take several minutes. If the SCADA-Server has successfully started up, the message: 250 SCALA STARTUP END … appears in the startup window. Note for redundant system: First start only SCADA-Server A.
3.3.2
START OF THE CAE-CLIENT AND LOADING THE DEFAULT CONFIGURATION
Start the CAE-Client via the Windows-Start-Menu START | PROGRAMS | 250 SCALA | CAE CLIENT. In the Login-window that appears click or the button [OK] without inputting a user name or password to login as Default-User. Start the consistency check in the CAE-Menu under TOOLS | CONSISTENCY CHECK. In the window that appears click the button [Start]. With that the standard configuration already available in CAE is checked for consistency and if free of errors is loaded automatically to the SCADA-Server. This process can take several minutes. With the help of the progress indicator and the associated text, one can follow the status of the consistency check. The consistency check and the subsequent loading is successfully concluded if the message "All data have been successfully loaded" is displayed in the notification display of the consistency check window. Then close the consistency check window with the button [Cancel].

RESTART OF THE SCADA-SERVER AFTER LOADING THE DEFAULT CONFIGURATION
After the first successful, complete loading it is recommended to restart the SCADA-Server (after each further loading a restart of the SCADA-Server is not necessary). To do this, click the close-window button of the SCADA-Server window. As a result the SCADA-Server is shut down. An End-Task window thereby appears. Here, do not click any button, instead wait for until the SCADA Server terminates itself!
If the SCADA-Server is completely shut down and the SCADA-Server window has disappeared, start the SCADA-Server again via the Windows-Start menu START | PROGRAMS | 250 SCALA | SCADA SERVER. Notice for redundant system: When the SCADA-Server A has completely started up, start also the redundant SCADA-Server B.
With a redundant system, when shutting down and restarting the entire system, it must be ensured that the Server which was ultimately active is started up as the first Server. If this sequence is not adhered to, then the Standby-Server can no longer be started up without manual intervention.
3.3.4
INITIAL START OF THE SCADA-CLIENT
The initial start of the SCADA Client is first possible after a complete consistency check and loading, because with this the user authorizations for the SCADA Client are also loaded to the SCADA Server. Now start the SCADA-Client via the Windows-Start menu START | PROGRAMS | 250 SCALA | SCADA CLIENT. In the Login-window that appears click or the button [OK] without inputting a user name or password, to login as Default-User. Afterwards the interface of the SCADA Client appears as configured by the standard configuration.

NOTES ON CONFIGURATION FILES
Further settings for the system are defined In SCADA-Server configuration files. These configuration files (*.str) exist in the directory \SAT\SCALA\prk\str\. These can be checked or modified preferably with Wordpad (Notepad can cause problems with line feed) or another editor. Configuration files become active when the SCADA-Server is started up, i.e. if you carry out changes here, a restart of the SCADA-Server is necessary to activate the changes.
Comments are to be found in the individual configuration files, carefully read through these before you carry out any changes in the configuration file. All configurations are already preset with sensible defaults after the installation of 250 SCALA, i.e. normally no changes must be made in the configuration file, and the system can be started without intervention in the configuration file.

OPC SERVER
The installation of the OPC server is a separate item within the installation of 250 SCALA. It makes no difference at all whether the SCADA server is installed on the same PC or not. The OPC server is installed together with the common components of 250 SCALA. These ensure the dialogues for "Settings" and the RSI parameters are available on the PC. The "OPC Core Components" of the OPC Foundation are also installed on the installation of the OPC server. These provide, for example, the OpcEnum service, and are a prerequisite for the use of a OPC server. This is automatic on installing 250 SCALA (as soon as the OPC server is installed. The OPC server from 250 SCALA can be installed on several PCs if so required. The data capacity offered by these OPC servers can vary. Installation of the OPC server is independent of the existing OPC client from 250 SCALA (available for some time) and can hence be performed on computers on which the OPC client is installed. A detailed description of the installation procedure can be found in the SCALA-Online-Help at Parameter Setting | OPC Server.

FDA EDITOR (LOGICAD)
As editor for FDA the product logiCAD is used. With the installation of FDA editor (logiCAD) through 250 SCALA, an empty project is created, which already contains the module libraries well known from CAEXplus. This project is proposed automatically during the first start of FDA editor (logiCAD). The module libraries contain CAEXplus specific components. These can be used also in the FDA 250project by what a large supply of prefabricated elements is available. These modules however are only available in the project which has been created by the installation process. Projects which are created further in FDA editor (logiCAD) do not provide these modules. The creation of further projects in FDA editor (logiCAD) is not recommended furthermore for reasons of the data backup. Only the data of the pre-designed project will be backed up. Moreover only the libraries of this sample project are updated in case of updates in future releases not those in individually created projects. Therefore it is strongly recommended not to design new projects, but rather to use the project proposed during the first start by FDA editor (logiCAD) and to adapt it to the project-specific needs. The procedure for the adoption of the sample project is as follows: •
start FDA editor (logiCAD).

UPDATE 250 SCALA
An update of 250 SCALA can be carried out if an older or the same version of 250 SCALA is already installed on the computer. If your 250 SCALA control system consists of a number of systems, the 250 SCALA product release for the CAE server must not be older than those of the other systems. The update requires on singular systems an operational interruption. Plan this impending operational interruption (that can take several hours) carefully. Inform the necessary stations and choose a favorable time. On a redundant system the update has to be executed first on the standby system. If this has booted completely a redundancy switch has to be carried out in order to update the other system. The following steps are necessary for the update of 250 SCALA and are described in detail in the following chapters: • • • • •
Data backup of the project data of the old (currently installed) version Update of the operating system (if necessary) Update of TOOLBOX II (if necessary) Update of the Program Package 250 SCALA Data backup of the project data of the new version (after the update) The entire 250 SCALA Update procedure must be carried out by a user who has Administrator-Authorizations.
The update supports all official versions since 6.00. For beta- and RC-versions an update is supported only within the same version. Example: The update from 6.42 beta 8 to the final version 6.42 is supported. The update from 6.41.01 beta 1 to the final version 6.42 is not supported. It is strongly recommended to perform a backup of the entire computer (e.g. image backup with Acronis TrueImage) prior to the installation.

UPDATE OF TOOLBOX II
For the new version of 250 SCALA it may be necessary to install a new Service pack for the TOOLBOX II or even a new version of TOOLBOX II. The update procedure checks the demands and gives corresponding messages if any demand of the new version of 250 SCALA is not fulfilled. Before each update, it is absolutely essential to back up data for TOOLBOX II via the Data Distribution Center so this can be accessed again at any time in the event of an emergency. A guide for updating the TOOLBOX II can be found in the TOOLBOX II-Documentation. If TOOLBOX II needs to be deinstalled for the update and a version older than 6.50 is still installed on the 250 SCALA CAE server, please note the following vitally important information: When uninstalling TOOLBOX II the project data of the 250 SCALA CAE-Server are also uninstalled, since both use the same database. It is therefore absolutely necessary to also carry out a backup of your 250 SCALA project data via SCALA Data Storage before uninstalling the TOOLBOX II, and to restore the backup of the CAE-Server again after a new installation of TOOLBOX II !
If Version 6.50 or higher is installed on the 250 SCALA CAE, this will not be affected if TOOLBOX II is deinstalled. If the TOOLBOX-requirements of 250 SCALA have not changed, then it is not necessary to update TOOLBOX II.

SECURITY
A security package for 250 SCALA will be available in 2011. This package contains measures to take into consideration increased security requirements for PC systems, with regard to virus scanners, virus signatures and patches for Windows and MS Office.
7.1
VIRUS SCANNER
Although the manufacturers of anti-virus software use all imaginable test mechanisms to avoid false positives, an element of risk always remains. This is due to the fact that no manufacturer of anti-virus software has access to all applications, files, in-house developments and functions that may occur within a company. ANDRITZ HYDRO has therefore set itself the goal of introducing a system for checking virus signatures (patterns) so that 250 SCALA is not negatively affected by false positives. Using a high-quality automated test environment, it should be possible to supply 250 SCALA customers with anti-virus patterns promptly. Starting with 250 SCALA version 6.50, ANDRITZ HYDRO will supply a system that is free of viruses at the point of acceptance/hand-over, as well as information on the current version of the virus scanner, checked on our test system. All future updates of the virus scanner will be checked in a test system, with a view to interplay with our software, and once they have passed the tests, they will be available to the customer for download via an interface, in so far as a service contract covering these services exists between ourselves and the customer. Prompt download by the customer is necessary for reliable virus protection, and the customer holds sole responsibility for this. Any liability on the part of ANDRITZ HYDRO for complete protection against viruses or other attacks, as well as for false positives, shall be excluded, as shall compensation for subsequent damage, on whatever grounds. The customer shall remain responsible for protecting its entire system against viruses.
7.2
OPERATING SYSTEM AND OFFICE UPDATES
With regard to operating system and office updates, from version 6.60, 250 SCALA will introduce a mechanism similar to that used for verification of the virus patterns. The aim is to carry out this test within approximately 8 weeks of the date on which a defined status of operating system update becomes available, and to authorize the update accordingly. The note regarding the service contract and liability also applies accordingly to the operating system updates.

250 SCALA DATA STORAGE
To be able to bring your project data up-to-date at any time due to an emergency, you should carry out regular data backups. You can make these data backups on the hard drive (e.g. in the directory \250 Backup\ ) and then e.g. burn onto CD or backup onto a network drive. Please note that the data storage directory must not be in the project- or data-directory. In particular before an update you should always make a data backup (or Acronis Image) of your project data.
A detailed description of backup and restore is to be found in the 250 SCALA Help, chapter Parameter Setting | Data Storage.

10 250 SCALA SETTINGS In the 250 SCALA settings, different important settings for 250 SCALA can be carried out. They are automatically called up at the end of the initial installation or an update of 250 SCALA, or can be called up via the Windows Start menu via Start | Programs | 250 SCALA | Tools | Settings
10.1 PROJECT
250 SCALA | Installation Manual for Windows Operating Systems D74-080-2.79
250 SCALA Settings
Page: 80 (total 156)
Projectname The "Projectname" is the project abbreviation, e.g. . This must be identical on CAE-Server and SCADA-Server (if CAE-Server and SCADA-Server are on the same computer, it is the case anyway) and is checked during loading from CAE-Server to the SCADA-Server. Exception is the "Multi-hierarchy". If "Multiple SCADA Systems" is activated (in other words "Multi-hierarchy" is used), it is important that the individual SCADA Systems in the "Multi-hierarchy" have different projectnames, since e.g. the "System identification constant" is derived from the projectname. Multiple CAE Projects The multi project handling provides to the user the possibility to administrate multiple 250 SCALA projects in a single CAE database. Up to 100 projects can be administrated. Up to 10 of these projects can be administrated at the same time. This option is meant especially as support to the efficient development of customer projects. This function is of less importance for an installed SCALA-system as usually not more than one project is in use. Language settings Here the "Project language" and the "Default language" can be selected. This setting refers to the corresponding language-column in the MLS-file. If no appropriate text is found in the MLS-file for the project language, then the text of the default language is used. Consequently, e.g. with only partial translation in the project language, the corresponding text of the standard language can always still be displayed. If the text is also not found in the default language, then it is displayed in the English language. Redundancy If the machine, is a non-redundant system, then "not redundant" has to be selected. If the machine is a redundant system, either "Server A" or "Server B" has to be selected (depending on which server this machine is). As soon as a SCADA Server has been selected, the until then grayed-out field "SCADA Server B" in "Server Network Names" becomes active. If no server is installed on this machine then it is not possible to select a server. Then it only has to be decided between "not redundant" and "redundant". (If "redundant" fill in the name of the server in "Server Network Names".)
250 SCALA | Installation Manual for Windows Operating Systems D74-080-2.79
250 SCALA Settings
Page: 81 (total 156)
Server Network Names Here the IP-address, the Host name or the Alias name of "SCADA Server A", "SCADA Server B" and "CAE Server" must be specified. When using the Software package "Schedule Manager", the Alias name may not be used.
"SCADA Server B" is only active if redundancy has been selected and "CAE Server" is only active if it is required for a component that is installed on the machine (e.g. CAE-Client). RSI Connection Timeout With "RSI connection timeout" activated, the "Connection Timeout" can be selected in seconds. This parameter specifies whether the SCADA-Server is to terminate the connection to a component coupled via RSI (e.g. SCADA-Client, RSI-SQL, VBSE, RAS, Program-Manager) after a preset time if a failure is detected. If "RSI connection timeout" is not selected, then the connection is terminated according to the TCP/IP Timeout (normally 3 Minutes). Normally, the default setting "RSI connection timeout" activated and the monitoring time of 30 seconds remain unchanged. SCALA Computer Name The computer name of the computer. Is adopted from the Windows-Settings. A change to "SCALA Computer Name" is not adopted in the Windows Computer Name. The SCALA Computer Name is required e.g. when using the component "Remote Application Starter Daemon (RAS Daemon)". SCALA should handle Windows Shutdown Provides that all running SCALA applications will be closed before shutdown, reboot or log off. If this option is not selected, all SCALA applications (SCADA-client, SCADA-server etc.) have to be closed manually before shutdown. Disable Windows Media Sense for TCP/IP Removing the network plug was till now the reason that also purely local connections (e.g. SCADA client to SCADA server at a compact configuration) were interrupted. If this checkbox is selected, then this does not happen any more. ATTENTION: If using DHCP ("obtain an IP-address automatically") after the change of the network the new IP-address must be requested manually with "ipconfig /renew".

Emulate Embedded System If this option is selected, SCALA behaves as an embedded system. By than the behavior of the parameterization of an embedded system can be emulated on a development PC. On an embedded system this option is not available. If "Emulate Embedded System" is selected, in addition the option "Harddisk available" is accessible.
10.2 SCADA CLIENT
Parameter Set Here further parameter-sets can be created or selected for the SCADA-Client in addition to the defaultparameter-set. All the parameters in this tab (and the advanced settings) are valid for the selected parameter set. For every new created parameter-set an additional SCADA-Client shortcut is created in the WindowsMenu (after pressing the button [OK] or [Apply] ). With this shortcut the SCADA-Client can be started easily with the predefined parameters. By pressing the button [New ...] a new parameter-set is created as a copy from an existing parameter-set. If the button [Remove] is pressed, the selected parameter-set is removed (the default-parameter-set cannot be removed).

250 SCALA Settings
Page: 83 (total 156)
Use CAE Defaults If this option is selected, the settings from "250 SCALA Settings" are taken over from the CAE. Excluded are only "Horn Sounds" and "Custom Graphic Acceleration". The values in the "250 SCALA Settings" then are grayed-out and instead the CAE defaults are used. Therefore this is reasonable only after the "250 SCALA Settings" are taken over into the "CAE Defaults" and in the CAE the SCADA Client has been updated. Details are to be found in the 250 SCALA Help: Installation | Overview | Instructions for CAE Upgrade to Version 6.42. SCADA Client Number Automatic assignment: This is the default setting. The number of the SCADA Client is assigned dynamically by the server (from 250 down to 128). Client number (1-100): If this option is selected, a number from 1 to 100 can be assigned to the installed SCADA Client. Client number range (1-100): If this option is selected, a certain number range can be assigned to the SCADA Client Number. Within this range the number is assigned dynamically by the server. Startup Under "Scheme" a scheme for the startup of the SCADA-Client can be selected, where e.g. special positions can be used (schemes can be defined in the CAE-Client). Via the parameter "Startup Script" a startup-script can be selected, that is activated automatically when the SCADA-Client starts up (Startup-Scripts can be defined via Dynadraw). Horn Sounds Here Wave-Files can be selected as horn sounds for the individual Software-Horns (1-16). If the checkbox next to "Horn Sounds" is deselected, all horn sounds are inactive ("Mute"; does not affect a possibly existing Hardware-Horn). In the dropdown-box a horn is selected; in the description field next to it the sound file for the respective horn sound is shown. The selection of the checkbox between these two fields causes that the respective horn will be regarded as non-existent. Custom Graphic Acceleration Here you can switch the use of the graphic acceleration of the graphics-card for the SCADA-Client on or off, which can be useful if there are problems with the graphics.

10.2.1 ADVANCED SETTINGS Via the button [Advanced Settings ...] in the tab "SCADA Client" the advanced settings for the SCADA-Client can be reached.
Redundancy This parameter is only changeable in an additional created parameter-set (is taken from tab "Project" in the default-parameter-set). If the machine, where the SCADA-Client connects to, is a non-redundant system, then "Not redundant" is to be selected, otherwise if the system is redundant select "Redundant". Server Network Names This parameter is only changeable in an additional created parameter-set (is taken from tab "Project" in the default-parameter-set). Here the IP-address, the Host name or the Alias name of "SCADA Server A" and "SCADA Server B" of the system where the SCADA-Client connects to must be specified. "SCADA Server B" is only active if redundancy has been selected.

RSI Connection Timeout This parameter is only changeable in an additional created parameter-set (is taken from tab "Project" in the default-parameter-set). This parameter specifies whether the SCADA-Server is to terminate the connection to the SCADA-Client after a preset time if a failure is detected. If "RSI connection timeout" is not selected, then the connection is terminated according to the TCP/IP Timeout (normally 3 Minutes). Custom SCADA Client Windows Size Here, a "Custom SCADA Client Window Size " for the SCADA-Client can be determined. Custom Monitor Resolution Here, a "Custom Monitor Resolution" for the SCADA-Client can be determined. Custom Monitor Usage Is used e.g. to use only two monitors to display the SCADA-Client on a system with 3 monitors. After activating "Custom Monitor Usage" the "Number of monitors used by the SCADA Client" can be determined. In addition, via "First monitor used by the SCADA Client" it can be determined, on which monitor (from left) the SCADA-Client is to be activated first. Auto Login Here a "Username" and "Password" for auto-login on startup of the SCADA-Client can be defined. Security If "Hide Desktop during SCALA Login" is activated, then while the Login-window of the SCADA-Client is visible, in the background a window is laid over the desktop, which prevents operation of the desktop. By activating "Auto Logoff on screensaver activation" a user-logoff from the SCADA-Client is performed automatically when the screensaver is activated. This parameter is not available under Windows NT. If "Allow 'Retain windows and current view' on logout/login": is selected, at Switch User the possibility to retain the current configuration of active displays (picture, curves, lists, …) in the SCADA Client is available.

Miscellaneous If "Touchscreen Mode" is activated the context-menus on selectable objects in pictures can also be opened via left-click. That makes it possible to operate e.g. on a touchpanel (without the right mouse-button). By activating "Hide Titlebar" the title-bar of the SCADA-Client is not visible. The parameter "Show as bottommost application" is used to show the SCADA-Client always as bottommost window, even if it is active. The advantage is that windows of applications that are started via the SCADA-Client cannot be hidden behind the SCADA-Client window. If this parameter is not selected the SCADA-Client comes to the front if it is activated. By activating "Use Watchdog" a message can be generated, if on the SCADA-Client for a selected time no input is given via keyboard or mouse. The tool bars of the SCADA-Client could not be covered already previously by pictures, lists or curves. The option "Toolbar Overlay Protection" prevents now also the covering of the tool bars by dialogues and applications. (See also references in the chapter "Tips & Tricks.) "Disable Splash Screen ": this option suspends the display of the Splash-Screen of the SCADA Client. This is useful e.g. when working via remote desktop, VNC, etc. "Hide cursor ": if selected, the mouse cursor is not displayed within the SCADA Client. This is useful on touch panels without a connected mouse. "Open virtual keyboard automatically ": if this option is selected, a virtual keyboard ("On-Screen Keyboard") is displayed automatically whenever a text box becomes active. Resource Level This setting determines up to which hierarchy level (starting with Basics) the resources will be used for display in the CAE-Client. Usually "Project" will be selected. Hint: The levels from Basics to Project are strictly hierarchical. I.e., Temp overwrites Basics and Project overwrites Temp. The behavior of the variants is slightly different. All variants are directly based on Project, i.e., changes in one variant do not affect the other variants. Menu Transparency With a slider the transparency of the context menu can be set from 0 – 75 %. In pictures the context menus of selectable objects (and only those menus) will be displayed transparent. By using the preview button the set transparency can be tested.

References to the Use of the Option "Toolbar Overlay Protection" To prevent that dialogues or applications can cover the toolbar, the option "Toolbar Overlay Protection" is available. (See chapter "Advanced Settings".) In this context the following references are to be considered: •
For using the Toolbar Overlay Protection, no user defined monitor assignment must be configured.
•
The standard menu bar is not part of the protected area.
•
Certain applications (e.g. Windows Task Manager) can overlay the toolbar.
•
In rare cases certain graphic cards can cause that a window comes to lie behind the toolbar. As it is then covered by the toolbar, it cannot be selected with the mouse. With the following procedure such a covered window can be recovered: −
select the window with the Windows-Taskbar, Task Manager or
−
press to make the window system menu visible
−
click "move"
−
move the window back to the visible area by using the cursor keys.

Nethorns Here, nethorns can be defined for use with 250 SCALA. For "Hardware (MAC) address" the MAC-address of the nethorn has to be specified (can be found on the nethorn device). The IP-address the nethorn should get, has to be defined under "IP address of the nethorn device". After powering off and on the nethorn device, it will get this IP address. The "Subnetmask of the nethorn device" normally is the subnetmask of the project-network. The "IP address of the gateway" only has to be specified if the nethorn device is reachable via a router, otherwise it can be left blank. SCA One can select between "Hardware solution" and "Software solution" for the SCA. This function is required for the correct mode selection and redundancy switchover. Under "Connection to the other server" the serial interface can be selected to which the HardwareSCA or (when using Software-SCA) the serial connection cable (between the two redundant SCADA-Servers) is connected. Under "Mode selection" when using Software-SCA one can set the desired mode, normally "Automatic". Use DNS for Orbix nameresolution This is only relevant when using VKMS. If "Use DNS for Orbix nameresolution" is activated, one can select a nameservice via "DNS domain". RTU send address mapping This parameter is only necessary if a redundant connection between SCADA-Server and RTU exists, and the RTU only has one IP address. In that case the SCADA-Server has to get more than one IP address. To do that the parameter "RTU send address mapping" has to be activated. Then the parameters "RTU send address 1" to "RTU send address 4" can be assigned to the different IP addresses of the SCADA-Server. These RTU send addresses can then be assigned to the connections as "#1" to "#4" in the CAE-Client under "LAN Components". Time Synchronization When "SCALA should synchronize the computers system clock" is activated, the system time of the computer is set by 250 SCALA. If an NTP-service is used to synchronize the system time of the computer, then "SCALA should synchronize the computers system clock" should be deactivated, since otherwise the computer clock would be synchronized from two places.

Status TA Here the text address of a binary information for the state monitoring can be entered. If nothing or a wrong text address has been entered, the state of the OPC server cannot be displayed. Visible Data Range Here can be set to which process variables released for OPC data exchange this OPC server grants access. To each data point up to 8 numeric OPC ranges can be assigned. A single OPC server then allows the access to those ranges released with this parameter. XML Portnumber The OPC server can be addressed via COM, DCOM und XML. In order that the access via OPC-XML works, here a TCP portnumber must be entered. It has to be paid attention that this number is not used by another application on this computer. If the portnumber is set to 0 then the XML functionality of the OPC servers is deactivated.

For the case of Windows logout or change user, the Autologon has NO EFFECT – you must fill in the Windows logon dialog nevertheless. An appropriate tool for activating Autologon is provided in the 250 SCALA product path (e.g.:\Programs\SAT\SCALA). Steps to go ahead: After the installation of 250 SCALA, in the directory \Program Files\SAT\SCALA\ there is the file ScalaAutologon.exe. Do start this program by double clicking it (without parameters). This program needs the Windows-Admin-user right in order to read and write the settings. (In contrast, that user, who should be set by the Autologon, does not need the Admin-user right. Therefore it might happen, that the Autologon user, later on when being the Windows user too, cannot read or can only partly read his own settings and cannot write any new settings at all.)

12.1 ACTIVATION OF AUTOLOGON After switching on the computer, the user scala250 should automatically be logged on. Do fill in the necessary values for • user • domain • password
(minimum is 1 character), e.g.: scala250 (may also be empty – if the PC is in a workgroup, then the PC name should be filled in) (0 till 128 characters), e.g.: scala500/2
into the appropriate fields.
The option Save password as encrypted text is available under Windows XP+newer, it is checked by default and the user should only uncheck it on special wish. NOTE: When saving plain text, the password will be un-encrypted in the Windows-Registry! Do click on Enable. This button is only available, if the Username field contains 1 character at least and if both Password fields have the same contents (here even an empty string is possible):
Restart the PC, Windows should then start up automatically with the user "scala250”.

12.2 DEACTIVATION OF AUTOLOGON If Autologon is already configured (only then the button is available), simply click on Disable:
Autologon now is deactivated. As a confirmation, a messagebox is displayed:
Then the program terminates.
Notice If the Shift key is pressed during startup before the system executes the logon, then Autologon is disabled for this one logon procedure. The Windows login dialog is displayed and must be completed.

13 NTP-CLIENT With Version V6.50 and higher of 250 SCALA, there is the option to install the TARDIS NTP client when installing 250 SCALA. It is possible to install an alternative NTP client, although this is not supported. With 64-bit Windows systems, a TARDIS cannot be configured via the control panel in the usual way once installed. For this reason, the Tardis Console feature is made available in the Tardis 2000 start menu during 250 SCALA installation. When user account control is active, this application must be specifically started with administrator rights.
13.1 TIP REGARDING 250 SCALA SETTINGS WHEN USING NTP
If NTP is used in the network, then in the tab "SCADA Server" under "Time synchronization" the setting "SCALA should synchronize the computers system clock" should be deactivated, since otherwise the computer clock would be time synchronized from two places.

15 TIPS & TRICKS 15.1 COMMON TRICKS AND TRAPS •
The format of one line in the hosts file is: . That means, the first name after the IP address has to be the "physical" name of the computer.
•
Do not drag SCALA shortcuts to the desktop or to the taskbar. Menu entries are updated correctly during the update procedure, shortcuts are not.
•
After the first successful load from the CAE client: restart the SCADA server.
•
The SCA hardware has to be connected to the COM1 interface.
•
For editing the configuration files (*.str) it is recommended to use WordPad; if not, line feeds are probably not recognized correctly.
•
Before update or "InitialStart": close all applications.
•
It is recommended to disable the Windows-Taskbar property "Always on top".
•
To avoid access to the operating system (CTRL-ALT-DEL, ALT-TAB etc.) we recommend installing the 250 SCALA feature "Windows Standard Operation". Additionally disable the user right "Windows standard operations" for the relevant user group in the CAE.
15.2 TCP PORTS Comprehensive documentation of the TCP ports required can be found in the document "TCP/UDP Portlist for 250 SCALA, SICAM 1703.

15.3 DPI SETTING FOR SCADA CLIENT The value must always be set to 96 DPI.
15.4 OPERATING 250 SCALA WITHIN A DOMAIN The "Roaming Profiles” function must not be used.
15.5 ENCRYPTING HARD DRIVE DATA For encryption of data on the hard drive, 250 SCALA supports the "Bitlocker” program (manufactured by Microsoft). Encryption can be carried out subsequently at any point, however we recommend that all 250 SCALA applications are closed for the duration of first encryption.

15.6 SUGGESTION FOR NETWORK ADDRESSING, NETWORK MASK AND HOST NAME ASSIGNMENT A computer incorporated in a TCP/IP-network has at least one network interface (mostly for Ethernet). This network interface has an IP-address. Each additional network interface over which the TCP/IP is operated requires a further, different IPaddress. Two devices that wish to communicate directly in a TCP/IP-network must each have IP-addresses within the same network address. If they do not have that, they can only communicate via a "Router". Physically separated networks each have their own network addresses. The network address is produced by logically linking the IP-address with the network mask (viewed binary) with AND. In the following descriptions, synonyms are used for the project-specific determinations: Project abbreviations
or in small letters:
Ethernet-Network address
With 250 SCALA, for each suggestion (no compulsory determination) due to the network mask 255.255.255.224 (hex: 0xffffffe0) a Class-C network address () assigned for a 250 SCALA project is separated into 8 further subnetworks (Subnetting, Subnetwork 0 to 7). With that 30 IP-addresses are available in each subnetwork. As a suggestion, the subnetworks are used within a project for e.g.: Subnetwork

Within the local Ethernet-Network (Subnetwork 0) there are therefore 30 IP-addresses available for up to 30 computers. Since there are no compulsory determinations for the assignment of network addresses in a 250 SCALA project, suggestions are made in the following table, how the address assignment in a project could meaningfully appear, this should be discussed with those responsible for the network before beginning the project and if necessary altered.

15.6.1 SUGGESTION FOR HOSTS-FILE The hosts-File, in which the Host-names and Alias-names of the computers in the project can be defined, is located in \WINNT\system32\drivers\etc\hosts . The hosts-File for the project network with two redundant All-In-One computers, two visualization workplaces, one protocol printer and one hardcopy-printer could e.g. appear as follows:
# # # # # # # # # # # # # # # # #
Copyright (c) 1993-1999 Microsoft Corp. This is a sample HOSTS file used by Microsoft TCP/IP for Windows. This file contains the mappings of IP addresses to host names. Each entry should be kept on an individual line. The IP address should be placed in the first column followed by the corresponding host name. The IP address and the host name should be separated by at least one space. Additionally, comments (such as these) may be inserted on individual lines or following the machine name denoted by a '#' symbol. For example: 102.54.94.97 38.25.63.10

Function and Task of Deactivated Services
Page: 131 (total 156)
17 FUNCTION AND TASK OF DEACTIVATED SERVICES 17.1 ACTIVE X INSTALLER SERVICE (AXINSTSV) The ActiveX Installer (AxInstSV) service provides user account control validation for the installation of ActiveX controls from the Internet and enables management of ActiveX control installation based on Group Policy settings. This service’s startup type is Manual, so it will start when requested by an application. If this service is disabled the installation of ActiveX controls will behave according to the default browser settings. By default it logs on using the Local System account. This service is not included in Windows Server 2008 R2. The ActiveX Installer service is dependent upon the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.2 ADAPTIVE BRIGHTNESS SERVICE (SENSRSVC) The Adaptive Brightness (SensrSvc) service monitors ambient light sensors to detect changes in ambient light and adjust the display brightness. If this services is stopped or disabled the display brightness will not adapt to lighting conditions. This service is configured for a manual start by default. When started it will log on using the Local Service account by default. This service is not dependent on any other system service, nor is any service dependent on it. This service is not included in Windows Server 2008 R2. This service is supported in all versions of Windows 7except Windows 7 Starter operating system.
17.3 APPLICATION LAYER GATEWAY SERVICE (ALG) The Application Layer Gateway Service (ALG) is a subcomponent of the Windows networking subsystem. It provides support for third-party plug-ins to allow network protocols to pass through the firewall and work behind Internet Connection Sharing. This service is installed by default and its startup type is Manual. When started in the default configuration it will log on using the Local Service account. This service is not dependent on any other system service, nor is any service dependent on it. The following table identifies the application protocol, network protocol, and ports used by the Application Layer Gateway Service: Application protocol

17.4 APPLICATION MANAGEMENT SERVICE (APPMGMT) The Application Management service (AppMgmt) provides software installation services such as Assign, Publish, and Remove. It processes requests to enumerate, install, and remove applications that are deployed through an organization's network by using Group Policy. When you use Get Programs from the Windows Control Panel to install programs from the network on a domain-joined computer, Windows calls this service to retrieve the list of deployed applications on your network. The service is also called when you use Control Panel to remove an application, or when a component (such as the shell) makes an installation request for an application to handle a file name extension, Component Object Model (COM) class, or ProgID that is not present on the computer. The service is started by the first call that is made to it, and it does not stop after it is started. If the Application Management service stops or if you disable it, users cannot install, remove, or enumerate applications that are deployed in AD DS. This service is installed by default but is not started unless an application requests it. When started in the default configuration it will log on using the Local System account. This service is available on Windows 7 Professional, Windows 7 Ultimate, and Windows 7 Enterprise as well as all versions of Windows Server 2008 R2. It is not available on Windows 7 Starter, Windows 7 Home Basic, or Windows 7 Home Premium. This service is not dependent on any other system service, nor is any service dependent on it.
17.5 BLOCK LEVEL BACKUP ENGINE SERVICE (WBENGINE) The Block Level Backup Engine Service (wbengine) performs block level backup and recovery of data. This service is used by the Backup and Restore feature in the Control Panel of Windows 7 and by the Windows Server Backup feature of Windows Server 2008 R2. It allows for backups to occur at the hard disk level, instead of just file by file, in a process similar to disk imaging. This service is installed by default and its startup type is Manual. When started in the default configuration it will log on using the Local System account. This service is not dependent on any other system service, nor is any service dependent on it.
17.6 BLUETOOTH SUPPORT SERVICE (BTHSERV) The Bluetooth Support Service (bthserv) supports discovery and association of remote Bluetooth devices. Stopping or disabling this service may cause already installed Bluetooth devices to fail to operate properly and prevent new devices from being discovered or associated. If you do not use Bluetooth devices with your computer, this service can be disabled. This service is installed by default and its startup type is Manual. When started in the default configuration it will log on using the Local Service account.

Page: 133 (total 156)
The Bluetooth Support Service is dependent upon the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.7 BRANCHCACHE SERVICE (PEERDISTSVC) The BranchCache (PeerDistSvc) service caches network content from peers on the local subnet. This enables clients in a branch office to securely retrieve files that are cached locally instead of having to retrieve files from a home office server. If this service is stopped or disabled remote computers will need to be able to connect directly to host servers in order to retrieve data. This service is installed by default on computers running Windows 7 Professional, Windows 7 Ultimate, and Windows 7 Enterprise and its startup type is Manual. When started in the default configuration it will log on using the Network Service account. The Branch Cache service is dependent upon the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.8 CERTIFICATE PROPAGATION SERVICE (CERTPROPSVC) The Certificate Propagation service (CertPropSvc) propagates certificates from smart cards to resources that request them. The Certification Propagation service applies when a logged-on user inserts a smart card into a reader that is attached to the computer. This action causes the certificates to be read from the smart card. The certificates are then added to the user's personal store. If the Group Policy "CertPropRootEnabledString" is set, Root Certificates are also propagated to the machine root trust store. Root certificate propagation is responsible for the following specific smart card deployment scenarios, where public key infrastructure (PKI) trust has not yet been established: • Joining the domain • Accessing a network remotely In both cases, the computer is not joined to a domain, and, therefore, trust is not being managed by Group Policy. However, the objective is to authenticate to a remote server (the domain controller or the RADIUS server). Root certificate propagation provides the ability to use the smart card to include the missing trust chain. On smart card insertion, the Certificate Propagation service propagates any root certificates on the card to the Smart Card Trusted Roots certificate stores on the local computer. This process establishes a trust relationship with the organization This service startup type is by default Manual. However, if you have deployed smart cards as part of your authentication policy, we recommend that you configure this setting with the Automatic startup type. When started in the default configuration it will log on using the Local System account.

The Certification Propagation service is dependent upon the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper The Certificate Services service supports the Active Directory Certificate Services (AD CS) server role as part of Windows Server 2008 R2 to enable a business to act as its own certification authority (CA). It issues and manages digital certificates for applications such as Secure/Multipurpose Internet Mail Extensions (S/MIME), Secure Sockets Layer (SSL), Encrypting File System (EFS), IPsec, and smart card logon. Windows Server 2003 supports multiple levels of a CA hierarchy and cross-certified trust network, including offline and online CAs. The AD CS server role is not installed by default. Administrators must install it through Server Manager, at which time the role service Certificate Services is also installed. If Certificate Services stops or if you disable it after installation, certificate requests are not accepted and certificate revocation lists (CRLs) and delta CRLs are not published. If the service stops long enough for CRLs to expire, existing certificates fail to validate. Certificate services can be used to issue and manage digital certificates for programs and protocols such as Secure/Multipurpose Internet Mail Extensions (S/MIME), Secure Sockets Layer (SSL), Encrypting File System (EFS), IPsec, and smart card logon. Certificate Services relies on RPC and on DCOM to communicate with clients by using random TCP ports that are higher than port 1024. Certificate Services is not supported on a Server Core installation of Windows Server 2008, but it is supported on a Server Core installation of as well as the Standard, Enterprise, and Datacenter versions of Windows Server 2008 and Windows Server 2008 R2. The following table identifies the application protocol, network protocol, and ports used by Certificate Services: Application protocol

17.9 DISTRIBUTED LINK TRACKING CLIENT SERVICE (TRKWKS) The Distributed Link Tracking Client (TrkWks) service maintains links between the NTFS file system files within your computer or across computers in your network domain. This service ensures that shortcuts and Object Linking and Embedding (OLE) links continue to work after the target file is renamed or moved. When you create a shortcut to a file on an NTFS volume, distributed link tracking stamps a unique object identifier (ID) into the target file, which is known as the link source. The file that refers to the target file (known as the link client) also stores information about the object ID internally. Distributed link tracking can use this object ID to locate the link source file in the following scenarios:
250 SCALA | Installation Manual for Windows Operating Systems D74-080-2.79

Page: 135 (total 156)
• When the link source file is renamed. • When the link source file is moved to another folder on the same volume or a different volume of the same computer. • When the link source file is moved to another computer in the network. Note Unless the computer is in a domain where the Distributed Link Tracking Server service is available, this form of link tracking is less reliable over time.
• When the shared network folder that contains the link source file is renamed. • When the computer that contains the link source file is renamed. For all of the preceding scenarios, the link source file must be on a fixed NTFS volume. The NTFS volumes cannot be on removable media. Note The Distributed Link Tracking Client service monitors activity on NTFS volumes and stores maintenance information in a file called Tracking.log, which is located in a hidden folder called System Volume Information at the root of each volume. This folder is protected by permissions that allow only the computer to have access to it. The folder is also used by other Windows services, such as the Indexing Service. If the Distributed Link Tracking Client service stops, any links to content on that computer are not maintained or tracked. By default this service is installed and starts automatically and logs on under the Local System account. The Distributed Link Tracking Client service is dependent upon the following system components: • Remote Procedure Call • DCOM Server Process Launcher • RPC Endpoint Mapper

The Function Discovery Provider Host (fdPHost) service provides the host process for Function Discovery providers. Function Discovery provides a uniform programmatic interface for enumerating system resources, such as hardware devices, whether they are local or connected through a network. It enables applications to discover and manage lists of devices or objects sorted by functionality or class. Users benefit from this categorized view of devices on their system. Both applications and users can use Function Discovery to discover what functions their system can perform, regardless of the underlying device or software architecture. Function Discovery supports an extensible discovery provider model. The providers included in the system provide an abstraction layer over existing standards such as Plug and Play, Simple Service Discovery Protocol (SSDP), Web Services Dynamic Discovery (WS-Discovery), and the registry. Custom providers can be created to expose your organization's resources through Function Discovery. The service startup type is Manual. When started in the default configuration the service will log on using the Local Service account.

17.13 INTERACTIVE SERVICES DETECTION SERVICE (UI0DETECT) The Interactive Services Detection (UI0Detect) service enables user notification of user input for interactive services, which enables access to dialog boxes created by interactive services when they appear. If this service is stopped, notifications of new interactive service dialog boxes no longer function and there may no longer be access to interactive service dialog boxes. This service supports the service isolation feature in Windows 7. In Windows XP, Windows Server 2003, and earlier versions of the Windows operating system, all services run in the same session as the first user who logs on to the console. This session is called Session 0. Running services and user applications together in Session 0 poses a security risk because services run at elevated privilege and, therefore, are targets for malicious users who are looking for a way to elevate their own privilege level. The Windows 7 and Windows Server 2008 R2 operating system mitigates this security risk by isolating services in Session 0 and making Session 0 noninteractive. In these operating systems, only system processes and services run in Session 0. The first user logs on to Session 1, and subsequent users log on to subsequent sessions. This means that services never run in the same session as users' applications and, therefore, are protected from attacks that originate in application code. Because Session 0 is no longer a user session, services that are running in Session 0 do not have access to the video driver. This means that any attempt that a service makes to render graphics fails. For example, if a device installer runs in Session 0 and the installation program creates a dialog box in Session 0 that requires user input to continue, the device installation never completes because the user does not see the dialog box. From the user's perspective, the device installer has stopped responding because it has stopped progressing and the user has no way to resume it. Basically, any functionality in a service or a service-hosted driver that assumes the user is running in Session 0 does not work correctly in Windows 7 and Windows Server 2008 R2. As a result of this issue, the option of enabling the Interactive Service Detection Service is available for customers who have services from earlier versions of Windows that send user interaction dialog boxes to Session 0 instead of the corresponding user's session. The service startup type is Manual by default. The service starts only when a visible dialog box that is not a command window is detected. If the service is started, users are notified when a dialog box or window (including a command window) appears in Session 0. Information about each of the last 10 dialog boxes appears in turn if more information is shown. This helps to ensure that deployment testers are aware of services from earlier operating systems in their environment and have the opportunity to contact the vendors for updated services. The service detects these visible dialog boxes or windows and sends a notification to the user. Users may choose to: • Respond to the dialog box immediately by clicking a button to switch to Session 0, interact with the task dialog box, and then switch back to their session. • Be reminded again in five minutes. The reminders continue until the dialog box closes. If this service is disabled, users do not receive notifications when the devices or services send dialog boxes to Session 0. By default this service logs on using the Local System account and is allowed to interact with the desktop. This service is not dependent on any other system service, nor is any service dependent on it.

17.17 NET.TCP PORT SHARING SERVICE (NETTCPPORTSHARING) The Net.Tcp Port Sharing Service (NetTcpPortSharing) provides the ability for multiple user processes to share TCP ports over the net.tcp protocol. This service allows a net.tcp port to be shared and secured in a similar fashion as port 80 is for HTTP traffic. The Net.Tcp Port Sharing Service is available on all operating systems that support .NET Framework 3.0, but the service is not enabled by default. As a security precaution, an administrator must manually enable the Net.Tcp Port Sharing Service prior to first use. Although the Net.Tcp Port Sharing Service does provide a layer of processing between applications and the network, applications that use port sharing should still be secured as if they were listening on the network directly. Specifically, applications that use port sharing should evaluate the process privileges under which they run. When possible, run your application using the built-in Network Service account, which runs with the minimal set of process privileges required for network communication. The Net.Tcp Port Sharing Service is included by default with Windows 7. It is available for installation as role service for the Application Server role on Windows Server 2008 R2. The Net.Tcp Port Sharing Service is not dependent upon any other system components. The following system component is dependent upon the Net.Tcp Port Sharing Service: • Net.Tcp Listener Adapter The Netlogon service maintains an encrypted channel between your computer and the domain controller that it uses to authenticate users and services.

The Offline Files service enables the user to designate particular network folders (and their subfolders) to be available offline. When the user is connected to the network, Offline Files service automatically synchronizes the folders to the local hard disk. When the computer disconnects from the network (in other words, to go "offline"), Offline Files service provides access to the content from the locally cached copy. When the computer reconnects to the network, the service automatically synchronizes any changes made offline with the online version and updates the offline versions with more recently made online versions. We recommend that you use Encrypting File System (EFS) to encrypt the Offline Files cache so that the files in the cache can only be accessed by the user on whose behalf it is cached. The Offline Files service is not available on computers running Windows 7 Starter, Windows 7 Home Basic, or Windows 7 Home Premium operating systems. It is installed by default and configured for an automatic start on computers running Windows 7 Professional, Windows 7 Ultimate, or Windows 7 Enterprise operating systems.

17.21 PEER NAME RESOLUTION PROTOCOL SERVICE (PNRPSVC) The Peer Name Resolution Protocol (PNRPsvc) service enables serverless peer name resolution over the Internet. If disabled, some peer-to-peer and collaborative applications may not function. This protocol enables the naming of computers and services without reliance on a DNS server. This allows for flexible, informal, temporary networks of nearby computers for collaboration, data sharing, and data storage. Security in peer-to-peer networks is difficult to establish. If computers in your organization are allowed to connect to peer-to-peer networks, a security policy about the types of information shared and the types of peer-to-peer networks that are compliant with your policy should be explicitly designed and communicated to your users to enable them to make decisions about which peer-to-peer networks they can trust. A trusted peer-to-peer network should be one that meets the industry standard for establishing trust: • The network uses a trusted authentication method to identify itself and its users. Your security policy should identify which form of authentication is the minimally acceptable method. • The network supports different authorization levels to allow for control over who you share information with by using the network. • The network supports encrypted data transmission so that when you collaborate by using this network, your information is not as susceptible to capture by unauthorized users. It should also provide some form of data-integrity checking such as digital signatures to ensure that the data was not modified in transit. This service is installed by default and its startup type is Manual. When started in its default configuration it logs on using the Local Service account. The Peer Name Resolution Protocol service is dependent upon the following system component: • Peer Networking Identity Manager The following system components are dependent upon the Peer Name Resolution Protocol service: • Peer Networking Grouping • PNRP Machine Name Publication Service

Users who walk away from computers that are running an active logon session create a security risk. To enforce the security of your system, it is best practice for users to disconnect from any remote Remote Desktop sessions and either log off or lock their computers when they leave. The smart card removal policy allows you to force users to comply with this practice when they remove their smart cards. Note If you decide to use the force logoff policy, users must ensure that they have saved changes to documents and other files before they remove their smart cards. Otherwise, they may lose any changes they have made.

17.39 WINDOWS CARDSPACE SERVICE (IDSVC) The Windows CardSpace (idsvc) service enables the creation, management, and disclosure of digital identities. Windows CardSpace is client software that enables users to provide their digital identity to online services in a simple and trusted way. It is known as an identity selector: when a user must authenticate to a Web site or a Web service, CardSpace presents a dialog box with a set of "information cards" for the user to choose from. Each card has some identity data associated with it— though this is not actually stored in the card—that has either been given to the user by an identity provider such as their bank, employer, or government, or has been created by users themselves. The CardSpace UI enables users to create Personal cards (also known as self-issued cards) and associate a limited set of identity data. When the user chooses a card, a signed and encrypted security token containing the required information (for example, name and address, employer's name and address, or credit limit) is generated by the identity provider that created the card. The user, in control at all times, then decides whether to release this information to the requesting online service. If

the user approves, the token is sent on to the requesting party where the token is processed and the identity information is extracted. This service is installed by default and its startup type is Manual. When started in the default configuration, it logs on using the Local System account.
17.40 WINDOWS COLOR SYSTEM SERVICE (WCSPLUGINSERVICE) The Windows Color System service (WcsPlugInService) hosts non-Microsoft Windows Color System color device model and gamut map model plug-in modules. These plug-in modules are vendor-specific extensions to the Windows Color System baseline color device and gamut map models. Stopping or disabling the WcsPlugInService service disables this extensibility feature, and the Windows Color System uses its baseline model processing rather than the vendor's requested processing. This might result in inaccurate color rendering. The Windows Color System provides for more precise color mapping and gradation. Non-Microsoft vendors such as printer manufacturers and photo finishers can use this feature in applications and drivers to explicitly call the color that they want rendered. This service is installed by default and its startup type is Manual. When started in its default configuration it logs on using the Local Service account. The Windows Color System service is dependent upon the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.41 WINDOWS CONNECT NOW – CONFIG REGISTRAR SERVICE (WCNCSVC) The Windows Connect Now - Config Registrar (WCNCSVC) service acts as a registrar for the Windows Connect Now service and issues network credentials to the enrollee in the service.

17.42 WINDOWS ERROR REPORTING SERVICE (WERSVC) The Windows Error Reporting Service (WerSvc) reports errors when programs stop working or responding and enables existing solutions to be delivered. It also generates logs for the Problem Reports and Solutions diagnostic and repair service. If this service is stopped, programs and services that rely on this service will not report errors correctly, and the results of diagnostic services and repairs for those programs and services will not be displayed. Windows Error Reporting is a feature that allows Microsoft to track and address errors relating to the operating system, Windows features, and applications. Windows Error Reporting gives users the opportunity to send data about errors to Microsoft and to receive information about solutions. Solution information can include instructions for working around a problem, or a link to the Windows Update Web site or another Web site for updated drivers, patches, or Microsoft Knowledge Base articles. Microsoft developers can use Windows Error Reporting as a problem-solving tool to address customer problems in a timely manner and to improve the quality of Microsoft products. Windows Error Reporting has "consent levels" that an administrator can configure to control how Windows Error Reporting sends data to Microsoft. These setting are configured in the Problem Reporting settings page of the Action Center Control Panel. These settings can also be configured through Group Policy under either Computer Configuration or User Configuration in Administrative Templates\Windows Components\Windows Error Reporting\Consent. User Account Control does affect how Windows Error Reporting works. A standard user does not have the same ability to report errors as an administrator does. If a prompt appears when a user is logged on as an administrator, the user can choose to report application and operating system errors. If a prompt appears for a user who is not logged on as an administrator, the user can choose to report application errors plus errors for operating system software that does not require administrative credentials to run. The administrator also has the option to specify a list of programs for which error reports should never be sent. This service is installed by default, and the startup type is Automatic.

On all other versions of Windows 7 its startup type is Manual. When started in its default configuration it logs on using the Network Service account. The Windows Media Player Network Sharing Service is dependent upon the HTTP system component.
17.46 WINDOWS REMOTE MANAGEMENT SERVICE (WINRM) The Windows Remote Management (WinRM) service implements the WS-Management protocol for remote management. WS-Management is a standard Web services protocol used for remote software and hardware management. The WinRM service listens on the network for WS-Management requests and processes them. The WinRM Service must be configured with a listener by using the Winrm command-line tool or by using a Group Policy setting in order for it to listen over the network. The WinRM service provides access to WMI data and enables event collection. Event collection and subscription to events require that the service be running. WinRM messages use HTTP and HTTPS as transports. The WinRM service does not depend on IIS but is preconfigured to share a port with IIS on the same computer. The WinRM service reserves the /wsman URL prefix. To prevent conflicts with IIS, administrators should verify that any Web sites hosted on IIS do not use the /wsman URL prefix. Windows Remote Management (WinRM) is one component of the Windows Hardware Management features introduced with Windows Server 2003 R2 that manage server hardware locally and remotely. These features include a service that implements the WS-Management protocol, hardware diagnosis and control through baseboard management controllers (BMCs), and a COM API and scripting objects that allow you to write applications that communicate remotely through the WS-Management protocol. WinRM provides an efficient way for management applications and scripts to communicate with local and remote computers by using an encrypted channel. The Windows service that WinRM installs and uses is also named WinRM.

When a server is connected to a BMC that supports the WS-Management standard, applications and scripts can use WinRM to communicate directly with the BMC, even when the operating system is offline (pre-boot or post-failure). When a server is not connected to a BMC, WinRM can still be used to connect to WMI remotely in situations where DCOM communication is impeded, for example, across a firewall. This usage is possible because the WS-Management standard uses a single port that is configurable by the system administrator. WinRM exposes its own application programming interface (API) for scripting, which can be used by scripts written in any Windows Script Host-compatible language. The scripting API communicates with WMI by using syntax different from standard WMI scripts. WinRM syntax is documented in the WinRM Software Development Kit. Hardware Management uses a WMI plug-in to expose WMI classes to WinRM. To call these classes, the WMI namespace and class must be converted into a Uniform Resource Identifier (URI). WS-Management is based on the following standard specifications: • HTTPS • SOAP over HTTP (WS-I profile) • SOAP 1.2 • WS-Addressing • WS-Transfer • WS-Enumeration • WS-Eventing As a security measure, if you use WinRM for remote management, you should configure the WinRM service to use the HTTPS protocol. This service is installed by default, and its startup type is Manual. When started in its default configuration it will log on using the Network Service account. WinRM is dependent on the following system components: • HTTP • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.47 WINDOWS SEARCH SERVICE (WSEARCH) The Windows Search (WSearch) service supports the Instant Search feature and provides content indexing and property caching for file, e-mail, and other content (by means of extensibility APIs). The service responds to file and e-mail notifications to index modified content. If the service is stopped or disabled, Windows Explorer cannot display virtual folder views of items, and search in Windows Explorer reverts to an item-by-item search.

The content indexed is based on the file and data types supported through add-ins included with Windows Search and the default inclusion and exclusion rules for folders in the file system. For example, the filters included in Windows Search support more than 200 common types of data, including support for Microsoft® Office documents, Office Outlook e-mail (in conjunction with the MAPI protocol handler), plaintext files, and HTML. The main component of Windows Search is the indexer process, which is implemented as a Windows service running in the Local System account. The process is always running for all users even if no user is logged on, enabling Windows Search to maintain one index shared among all users with security restrictions on content access and to process remote queries from client computers on the network. The Windows Search service includes a number of features to ensure that it protects the user experience and system performance when indexing. A number of conditions cause the service to throttle back or pause indexing: • High CPU usage by processes that are not search-related • High system I/O rate including file reads and writes, page file and file cache I/O, and mapped file I/O • Low memory availability • Low battery life • Low disk space on the drive storing the index This service is installed by default, and its startup type is Automatic. The Windows Search service depends on the following system components: • Remote Procedure Call (RPC) • DCOM Server Process Launcher • RPC Endpoint Mapper
17.48 WINDOWS TIME SERVICE (W32TIME) The Windows Time (W32Time) service maintains date and time synchronization on all computers on a Windows network. It uses the Network Time Protocol (NTP) to synchronize computer clocks so that an accurate clock value, or timestamp, can be assigned to network validation and resource access requests. The implementation of NTP and the integration of time providers make Windows Time a reliable and scalable time service for administrators. For computers that are not joined to a domain, you can configure the Windows Time service to synchronize time with an external time source. If this service is turned off, the time setting for local computers is not synchronized with any time service in the Windows domain or external time service. The Windows Time service is installed by default and configured for a manual start. When started in the default configuration is will log on using the Local Service account.
250 SCALA | Installation Manual for Windows Operating Systems D74-080-2.79
Function and Task of Deactivated Services
Page: 156 (total 156)
If the Windows Time service stops or if you disable it, date and time synchronization is unavailable in the network or from an external NTP server. There are two possible scenarios: • If you stop the Windows Time service on a workstation, the workstation cannot synchronize its time with another source, but no other external server is affected. • If you stop the Windows Time service on a domain controller, the same effect as in the previous scenario applies, but domain members are also unable to synchronize time with it. This inability to synchronize may adversely affect time synchronization in the organization. By default, the Windows Time service is installed and started automatically on computers running Windows 7 or Windows Server 2008 R2.
17.49 WLAN AUTOCONFIG SERVICE The WLAN Autoconfig service enables automatic configuration for IEEE 802.11 wireless adapters for wireless communications. Microsoft has worked with 802.11 network-adapter vendors to automate the network adapter configuration process, which associates the network adapter with an available network and improves the wireless roaming experience on Windows. The wireless network adapter and its Network Driver Interface Specification (NDIS) driver must do little more than provide support for a few new NDIS object identifiers (also known as OIDs) that query and set device and driver behavior. The network adapter scans for available networks and passes the information to Windows. The Wireless Configuration service configures the network adapter for an available network. When two networks cover the same area, the user can configure a preferred network order; the computer tries each network in order until it determines an active one. It is also possible to limit association to only the configured, preferred networks. On Windows Server 2008 R2 and Windows 7, the WLAN AutoConfig (WLANSVC) service enumerates wireless adapters, and manages both wireless connections and the wireless profiles that contain the settings required to configure a wireless client to connect to wireless networks. The WLAN AutoConfig System Services Group Policy settings in Windows Server 2008 R2 enable administrators to specify the service startup type of the WLAN AutoConfig service for domain member computers running with Windows 7 and Windows Server 2008 R2 that have wireless network adapters and the associated Windows 7 adapter drivers installed. WLAN AutoConfig Group Policy settings enable administrators to prevent domain member users from altering the startup mode of the WLAN AutoConfig service.
