We have an SBS 2003 with users having roaming profiles. Their profiles are stored on a drive on the server. This works just fine.
One user found it took an age to log on. When we looked at his profile, it had lots of videos and was 70GB in size.
He didn't need/want the videos so we deleted them and he was able to log on as normal.
This worked for a few weeks and the same thing happened again - the videos which we had deleted had come back... we have deleted them again but why do they keep coming back?
