Windows Server 2012 - No Remote Desktop License Servers Available...


Sometimes on Windows Server 2012 (R2) Remote Desktop farm you start receiving error, "The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license. Please contact the server administrator.", while trying to connect using Remote Desktop or Remote App .

  
 
The solution to fix this error is to delete a registry key related to Grace Period.

Open registry editor (regedit) and go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod

Delete GracePeriod key (folder).

Restart the server.
  
 
 
Note: remember you might have to repeat this every 120 days.
