Configuring License Settings on a Terminal Server

Updated: March 15, 2010

Applies To: Windows Server 2008

After you install and configure the Terminal Services license server, you need to configure your terminal server by doing the following:

The Terminal Services licensing mode determines the type of Terminal Services client access licenses (TS CALs) that a terminal server requests from a license server on behalf of a client computer that is connecting to the terminal server.

ImportantImportant
The Terminal Services licensing mode that is configured on a terminal server must match the type of TS CALs that are available on the license server.

For more information about TS CALs, see Terminal Services Client Access Licenses (TS CALs).

The Terminal Services licensing mode for the terminal server can be set in the following ways:

  • During the installation of the Terminal Server role service in Server Manager, on the Specify Licensing Mode page in the Add Roles Wizard.

    On the Specify Licensing Mode page, you can select Configure later if you are unsure during the installation whether to select Per Device or Per User. If you select Configure later, each time you log on as an administrator to the terminal server, a message will appear in the lower-right corner of the desktop reminding you that you need to configure the licensing mode for the terminal server.

  • By configuring the Terminal Services licensing mode for the terminal server by using the Terminal Services Configuration tool.

    If the Specify the Terminal Services licensing mode choices are dimmed and you cannot make a selection, the Set Terminal Services licensing mode Group Policy setting has been enabled and has been applied to the terminal server.

  • By applying the Set Terminal Services licensing mode Group Policy setting.

    This Group Policy setting is located in Computer Configuration\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Licensing and can be configured by using either the Local Group Policy Editor or the Group Policy Management Console (GPMC). Note that the Group Policy setting takes precedence over the setting that is configured in Terminal Services Configuration.

For more information about Group Policy settings for Terminal Services, see the Terminal Services Technical Reference (http://go.microsoft.com/fwlink/?Linkid=89673).

Use the following procedure to specify the Terminal Services licensing mode on a terminal server by using Terminal Services Configuration.

Membership in the local Administrators group, or equivalent, on the computer that you plan to configure, is the minimum required to complete this procedure.

  1. On the terminal server, open Terminal Services Configuration. To open Terminal Services Configuration, click Start, point to Administrative Tools, point to Terminal Services, and then click Terminal Services Configuration.

  2. Under Licensing, double-click Terminal Services licensing mode.

  3. Select either Per Device or Per User, depending on which is appropriate for your environment, and then click OK.

A terminal server must be able to contact (discover) a Terminal Services license server to request Terminal Services client access licenses (TS CALs) for users or computing devices that are connecting to the terminal server.

The license server discovery mode for the terminal server can be set in the following ways:

  • By configuring License Server discovery mode for the terminal server in the Terminal Services Configuration tool.

    If the Specify the license server discovery mode choices are dimmed and you cannot make a selection, the Use the specified Terminal Services license servers Group Policy setting has been enabled and has been applied to the terminal server.

  • By applying the Use the specified Terminal Services license servers Group Policy setting.

    This Group Policy setting is located in Computer Configuration\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Licensing and can be configured by using either the Local Group Policy Editor or the Group Policy Management Console (GPMC). Note that the Group Policy setting takes precedence over the setting that is configured in Terminal Services Configuration.

For more information about the license server discovery process, see Terminal Services License Server Discovery.

ImportantImportant
To see which license servers the terminal server discovers, and to be alerted to possible licensing discovery and configuration issues, use Licensing Diagnosis in Terminal Services Configuration. For more information about Licensing Diagnosis, see Troubleshooting TS Licensing Installation.

For more information about Group Policy settings for Terminal Services, see the Terminal Services Technical Reference (http://go.microsoft.com/fwlink/?Linkid=89673).
