We recently had an issue on site where a random couple of servers where experiencing Terminal Server Licence issue.  The servers in question were getting Event 1069 – TerminalServices-RemoteConnectionManager messages in the system log with the following detail;

As this was a large Citrix environment (1000s of servers), the resulting impact was the end user was unable to log on or identify what servers they were hitting.  The correct GPO settings to set the Remote Desktop License Server was already set and for reasons unknown the keys or a setting was corrupt so the server stopped connections both ICA and RDP).

To resolve the issue, you needed to find (see Blog – EventCombMT.exe) and log onto the affected server

Run GPEDIT.MSC

Navigate to  Computer Configuration\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Licensing

Double Click on Use the Specified Remote Desktop License Server

Click  Enabled

Add the Remote Desktop License Server hostname

Click  OK

Then Restart the following Services

Remote Desktop Services

Remote Desktop Configuration

Once this had been done, you should be able to remove the setting and the GPO should take effect.  We had a call open with Microsoft and they were unable to shed light on why this had happened but setting the key locally seemed to kick start the RDS License Acquire Process.
