Some time when you are working with sever you might install the remote desktop licence server role by mistakenly or purposely.
Have you ever noticed that there is a expire date for that service & need to buy separate licence for the client?
I have install that service by purposely and i have forgotten to remove the role from the server.
so after one month later I got below message even I don't know why it could happens.
So after read some forum I have realized that the issue is from the licence manager of the remote desktop role that I have added earlier.
So I removed the role and restarted the server. And remote desktop started working as usual.
