Our network has recently been upgraded to XP rather than 2000 and we're experiencing VERY slow logoffs. Login is quick and painless, but logging off takes 5 minutes sometimes. Any ideas where to start?

Event Viewer isn't being very helpful. No errors in there during logoff, so I'm guessing some service is having a hard time being shut down before the roaming profile can do its thing.

try with een clean profile, if this helps renew de ntuser.dat in your profile

with a clean one (from the default profile for ex.)

The only thing you will see is that a lot of settings you made will be lost.

It helps here, otherwise a new clean profile is the best!

Hope it helps
