SYMPTOMS

When you reconnect to a disconnected Terminal Services session on a different computer from the one on which you originally established the connection, the clientname variable retains the computer name of the computer on which you created the original session.

CAUSE

This problem occurs because when you reconnect to a disconnected session, Terminal Services does not verify whether the client computer has changed.
