| You are now ready to install the applications that were specified as image application during the Applications section of the Design phase. In order to install an application on a Terminal Services server you need to configure the server for install mode. Terminal Services uses a special installation mode for installing applications for multi-user use. This mode is activated by installing an application through the Control Panel Add/Remove Programs applet or by using the command "Change User /Install" prior to installing an application. Once you have finished installing the application you are required to return to normal execution mode by using the command "Change User /Execute". The default Terminal Services mode is Execution mode. The server starts in Execution mode when you start the system. The system is not operating in a global fashion when it is in Execution Mode. That is, the system expects many concurrent user sessions. This requires that the system keep sessions completely separate from each other, including the user at the system console. For instance, every user has a Windows and Windows\System directory that no one else uses. If an application requests the location of the system root, the system will point the application to the user's Windows directory rather than the actual Terminal Services system root. The following is the command switch available for the change user command. | Y:\>change user /? Change Install Mode. CHANGE USER {/EXECUTE | /INSTALL | /QUERY} /EXECUTE Enable execute mode (default). /INSTALL Enable install mode. /QUERY Display current settings. | Important! If you will be implementing client to server content redirection and you install an application(s) that you would like to take advantage of client to server redirection with then you will need to update the IMA data store with the latest file types from the local registry. To do this right click on the server that the application(s) were installed on and click Update File Types from Registry.
