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.
