First, the server places some of the kernel's memory address space into virtual memory. This allows what would be conflicting requests in a single-user environment to be processed properly in the multi-user environment, and for multiple instances of kernel-mode device drivers to be loaded and used by multiple users the reason why one user can technically crash the whole system.

Some system processes are not session-specific, meaning that all users in all sessions will need access to them. These processes are stored in a single global memory area shared by all users. A side-effect of sharing processes like this in a Terminal Server environment is that sometimes you'll run into processes that are not "session aware.

Since there's usually no one in the server room to acknowledge the message, there is the potential to prevent a user's application from continuing. If the multi-user kernel is the foundation of server-based computing in Windows Server , the Terminal Service is the cornerstone. This service loaded via termserv. After the server's console keyboard, video and mouse drivers is loaded, the Terminal Service initiates the Session Manager subsystem smss.

A new session is created each time a user logs onto Terminal Server. A session essentially consists of a virtual desktop from which the user can run applications and with which he can interact just as with a workstation. A server session should not be confused with the server console, since a session is not a remote control of the console but actually a new desktop separate from the console.

Each time a user connects to a Terminal Server and creates this "virtual desktop," a unique session ID number is created to differentiate the user and therefore the user's processes from all other sessions and users.

Session IDs also enable the server to keep memory separate for each user's session. When a user logs off from a Terminal Services client, the session that was being used is deleted and the processes and memory that were launched and used by that session are removed.

Each Terminal Server tracks its own Session IDs and handles the task of issuing, tracking, and removing them. Since server sessions are "virtual" and memory and processes are kept separate between sessions , an application crash or lockup in one session should not affect any other user sessions, even if other users are using the same application.

However, the key phrase here is "should not" affect other users. Even though user sessions are separate on a server, they still share server resources and certain segments of code. If one user invokes a process that causes the server to blue screen, this will obviously have an effect on the other users. On the other hand, simple occurrences like an application hanging on a timed out request or Microsoft Word crashing when a user opens a corrupt document will not be seen by the other users within their own sessions on the system.

Since a session is really a user's desktop, there are times that a session can be in various different states, much like a normal workstation. For example, if a user walks away from their workstation for a period of time, the workstation does not turn off. Rather, it is merely idle, waiting for user input. Terminal server sessions behave much the same, and can be in one of a number of different states depending on the user's activity or inactivity , connectivity between the client and server, and session time out settings.

Figure 2. In most environments, administrators configure sessions with various timeouts. You can limit the amount of time that a single session can be open, or you can automatically convert an idle session to a disconnected session. You can use one of the following methods to obtain transitional CAL licenses, depending on how you obtained the Windows XP Professional operating system licenses.

You must provide your volume licensing program information Enrollment number, Agreement number, or License and Authorization numbers, depending on the program type together with the requested number and type of terminal server CAL tokens.

The information that you enter in the Terminal Server Licensing utility is validated by Microsoft Clearinghouse, and when your request for tokens is within the boundaries of the entitlement program, license tokens are installed in the Terminal Server License Server. If you obtained your Windows XP Professional licenses through a retail or an OEM channel, these licenses will have a product key included.

You can find the product key on the retail packaging or on the Certificate Of Authenticity COA sticker on the computer case.

To obtain a transitional CAL license, follow these steps:. In the License Type list, click the type of license that you want to obtain, type your e-mail address in the eMail Address box, and then click Next.

In the Terminal Server Licensing utility, enter the license token s that you received. Quick access. Search related threads. Remove From My Forums. Answered by:. Archived Forums. Remote Desktop Services Terminal Services. Sign in to vote. Tuesday, May 29, PM.
