When logging off from a Windows 2000, XP or 2003 machine system processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment.
Therefor, always install the User Hive Cleanup service from Microsoft:

After doing so i’ve seen some errors in the eventviewer when using Symantec Antivirus v10 or Endpoint Protection. These programs have “Tamper Protection” which means they will block programs from messing around with the main processes from Symantec.
In this case it’s actually pretty clear who’s blocking the registry :)
