I took over a client recently with 25+ users running a variety of 98, Me, and XP computers. It is a law office (they are very cheap) and they are using terminal services to work off of a 2003 server (not a DC) and mainly use WordPerfect to do their normal business functions. About once or twice a week, I have to remote onto the server to reset a user under Terminal Services Manager, since their screen just froze up and cannot do anything. It deals with their terminal services session, since once I reset it they can log on normally and function fine. I can't seem to figure out why that randomly happens.
It usually seems to happen while the user is working on WordPerfect. No other users are affected at the time of the lockout, so it randomly affects different accounts at different times. I cannot associate the lockout with a specific activity by the user or other terminal services users. Any ideas?
