New Terminal Server clients, Terminal Services clients, or Remote Desktop Connection clients may connect to Terminal Services correctly, but some existing clients that could previously connect may be unable to connect. If an existing client cannot connect, the following error message may be displayed on the client computer:
Terminal Server has ended the connection
In all cases, clients can connect as if they were new clients if you delete the license from the client.For additional information about deleting licenses, click the article number below to view the article in the Microsoft Knowledge Base:

This is most likely to occur because the original issuer of the temporary license cannot be contacted by the Terminal Services server. This may occur because the license server has been rebuilt or is currently unavailable.

This may also affect clients running third-party operating systems or other Microsoft clients that may not be explicitly listed.
