This error usually happens if the server is unable to contact the RDS Licensing server that it’s configured to contact. Most probably cause would be that your system might have lost the domain trust or part of a different domain while this error happens.
I encountered this scenario when I rejoined my App RDS/terminal server to the domain as it lost it’s domain trust but haven’t rebooted the after rejoining the domain.
