Configure 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 configure the Terminal Server Licensing mode

Using Group Policies (best practice)

  1. Open Group Policy.

  2. In Computer Configuration, Administrative Templates, Windows Components, Terminal Services, double-click Terminal Server Licensing Mode.

  3. Click Enabled.

  4. Click 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.

Important

  • You should thoroughly test any changes you make to Group Policy settings before applying them to users or computers. For more information on testing policy settings, see Resultant Set of Policy.

Notes

  • 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.

  • This Group Policy setting is only available on Windows Server 2003 with Service Pack 1.

  • Use this procedure to configure the local Group Policy object. To change a policy for a domain or an organizational unit, you must log on to the primary domain controller as an administrator, and then open Group Policy by using the Active Directory Users and Computers snap-in.

  • Group Policy overrides the configuration set with the Terminal Services Configuration tool.

  • 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.

Using Terminal Services Configuration

  1. Open Terminal Services Configuration.

  2. In the console tree, click Server Settings.

  3. In the details pane, right-click Licensing Mode, 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.

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.
