You did perform the REPAIR INSTALL?

So I am an AV tech an Babson college and I recently came accross a problem that my IT department can't solve (or don't want to). One of our office computers running Windows XP does not let anyone log on to a computer where someone had just logged off. After someone loggs off the computer the only way to log back on is to log on to the guest account first then log off and sometimes you can log onto another user. I have found nothing about this in my google search so I turned here...
