Why do my Terminal Services clients disconnect upon connection?

A. When your Windows 2000 Server Terminal Services clients try to connect to a server, you might receive the following error message:

Terminal Services Client Disconnected. The Terminal server has ended the connection.

A server without a valid Terminal Services license causes this error. When you install Terminal Services, you have a 90-day temporary license. After the 90 days expire, clients won't be able to connect. The only solution is to purchase a valid license.
