I have installed Terminal Services and Terminal Services Licensing on a 2008 SP2 Domain Controller. I have an Open License for Terminal Services and I have successfully Activated the Licensing server and all looks good in the TS Licensing Manager. TS Cal Availability is Available and when I log users on TS Cals In Use shows the correct figure. The Server is also showing as Activated.

However, if I open Server Manager, Expand Roles, Terminal Services, Terminal Services Configuration and click on Licensing Diagnosis I get the following warning:

The Terminal Server is within its grace period, but the terminal server has not discovered any license servers.

I have tried changing License Server Discovery Mode from Automatic to the FQDN of the server. When I click Check Names I get a message stating it is a valid license server, however the warning message still remains. Even after a reboot it is still there.

I have also tried uninstalling Terminal Services and TS Licensing and reinstalling but I still get the same message. I cannot see anything obvious in the event viewer. Could someone please help me with this?

Thanks in advance.

This may sound silly but I know this has caused panics in my environments before. Make sure you are logged into the terminal server as a domain user with proper privs (or launch the mmc as a domain user). The licensing diagnosis will not complete the queries properly if logged in using a local account on the TS box.

I am logging on as a domain admin (the server is a DC). – hulbs9nw Aug 25 '09 at 10:41

Have you done this.

Thanks for the tip, I have just tried that and the server is correctly listed. This is definitely a strange one. – hulbs9nw Aug 25 '09 at 10:42
