Remote Session Disconnected

Your remote session may be disconnected with the message: "The remote session was disconnected because the terminal server client access license stored on this computer has been modified"
At this point you should remove the saved terminal server licenses from the client registry. Delete the following key from the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing

The key will be created the next time you log on to the Terminal Server.
