Event ID 75 — Terminal Services Per User Client Access License Tracking and Reporting

Updated: January 5, 2012

Applies To: Windows Server 2008

red

In Windows Server 2008, you can use the TS Licensing Manager tool to create (generate) reports to track the Terminal Services Per User client access licenses (TS Per User CALs) that have been issued by a Terminal Services license server. TS Per User CAL tracking and reporting is supported only in domain-joined scenarios because the information about the TS Per User CAL that has been issued to a user is stored as part of the user account in Active Directory Domain Services (AD DS).

For TS Per User CAL tracking and reporting to work, the computer account for the license server must be a member of the Terminal Server License Servers group in AD DS. If the license server is installed on a domain controller, the Network Service account must also be a member of the Terminal Server License Servers group.

Resolve

Add the license server to the Terminal Server License Servers group and restart the Terminal Services Licensing service

To resolve this issue, do the following:

  • Add the computer account for the license server to the Terminal Server License Servers group in Active Directory Domain Services (AD DS).
  • Restart the Terminal Services Licensing service on the Terminal Services license server.

To perform these tasks, refer to the following sections.

Note:  If the license server is installed on a domain controller, the Network Service account also needs to be a member of the Terminal Server License Servers group.

Add the computer account for the license server to the Terminal Server License Servers group

You can add the computer account for the license server to the Terminal Server License Servers group in AD DS either by using TS Licensing Manager or by using Active Directory Users and Computers. To perform these tasks, refer to the following sections.

Add the computer account by using TS Licensing Manager

To perform this procedure, you must have membership in the local Administrators group on the license server and membership in the Domain Admins group in AD DS, or you must have been delegated the appropriate authority.

To add the account to the group:

  1. On the license server, open TS Licensing Manager. To open TS Licensing Manager, click Start, point to Administrative Tools, point to Terminal Services, and then click TS Licensing Manager.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the left pane, click All Servers, click the name of the license server, and then on the Action menu, click Review Configuration.
  4. In the Configuration dialog box, click Add to Group.

    Note:  If Add to Group does not appear in the Configuration dialog box, the computer account for the license server (and the Network Service account) are already members of the Terminal Server License Servers group and no further action is required.

  5. Click Continue, and then click OK.
  6. Restart the Terminal Services Licensing service on the license server. To restart the Terminal Services Licensing service, see the section titled "Restart the Terminal Services Licensing Service."

Add the computer account by using Active Directory Users and Computers

To perform this procedure, you must have membership in the Domain Admins group in AD DS, or you must have been delegated the appropriate authority.

To add the account to the group:

  1. Open Active Directory Users and Computers. To open Active Directory Users and Computers, log on to a computer where Active Directory Users and Computers is installed (for example, an AD DS domain controller), click Start, click Run, type dsa.msc, and then click OK.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

  8. Click OK, and then click OK.
  9. Restart the Terminal Services Licensing service on the license server. To restart the Terminal Services Licensing service, see the section titled "Restart the Terminal Services Licensing service."

Restart the Terminal Services Licensing service

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.
