Terminal Server license server – NOT ACTIVATED!
Written by Aaron Silber:
Just ran into an issue where all of a sudden people could not log into the TS Servers any more. When I looked at the license server, I noticed that all of a sudden my TS License server (running on a Windows 2008 Domain Controller) which had been working fine and without issues, all of a sudden was reporting that it was not activated.
Weird I thought, but ok I guess I’ll just reactivate it, sounds simple enough right? Not so fast, attempting to reactivate produced this lovely message:
The Activate Server Wizard encountered an internal error from the license server : Message Number: 0xc0110011
Luckily a quick check on the Microsoft KB turned up a hotfix to correct this issue, something to do with corrupt certificate and/or a certificate that is part of the digital certificate chain expires. The Microsoft hotfix to resolve this issue can be downloaded from this KB article: https://support.microsoft.com/kb/983385
