Usually when one complains, they all start calling.

Are all the users slowed down at once, or is it just one user at a time?
I had a customer's TS where a user's session would slow to a crawl, and
none of the perfmon counters seemed out of the ordinary. I found that,
in every case, winword.exe was running in the user's session. If I
stopped that task, the session would pick right back up. The last
attempt at a fix was a complete reinstall of Office, and the last time I
checked with them, they hadn't seen the problem.
