Set the terminal server licensing mode

Updated: January 21, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To set the terminal server licensing mode

  1. Open Terminal Services Configuration.

  2. In the console tree, click Server Settings.

  3. In the details pane, right-click Licensing, and then click Properties.

  4. Select either Per User or Per Device, and then click OK.

    A Per Device CAL gives each client computer or device the right to access a terminal server that is running Windows Server 2003. A Per User CAL gives one user the right to access a terminal server from an unlimited number of devices.


  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.

  • To open Terminal Services Configuration, click Start, click Control Panel, double-click Administrative Tools, and then double-click Terminal Services Configuration.

  • Group Policy overrides the configuration set with the Terminal Services Configuration tool. For information about how to configure the Terminal Server Licensing mode option by using Group Policy, see Configure the Terminal Server Licensing mode.

  • By default, when the Per Device licensing mode is used, after a client logs and authenticates to a terminal server for the first time, and after the terminal server locates a license server, the terminal server issues the client a temporary license. After a client logs on and authenticates to a terminal server for the second time, if the license server is activated and at least one Per Device CAL is installed on the license server and not yet issued, the terminal server issues the client a permanent, Per Device CAL. Per User CALs are not monitored by Terminal Server. This means that even though there is a Per User CAL in the license server database, the Per User CAL is not decremented when it is used. Additionally, if you use the Per User licensing mode, when a client logs on to a terminal server for the second time, the temporary license is not upgraded to a permanent CAL.

  • Users can create more than one session by specifying a different program to start on connection for each session.

  • For more information about Terminal Server and Terminal Server Licensing, see Guidelines for Deploying Terminal Server (http://go.microsoft.com/fwlink/?LinkID=34627) and Windows Server 2003 Terminal Server Licensing (http://go.microsoft.com/fwlink/?LinkID=26220).

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
