I have quite a few Server 2012 RDS Servers running and every so often no one can login due to a licensing issue. The fix is to delete the Grace Period registry key. I'm sure this shouldn't keep happening. My research tells me that if I set the mode to per user and make sure the server is pointing to itself for its licensing this should work but we do still keep getting the error every 120 days. It seems like a bug but all servers are fully patched. Would anyone know a permanent fix?
Thanks
Dave
