Deleting roaming profiles
When using roaming profiles we often experiences, that there roaming profiles are not deleted locally from the users desktop, even though we have set the DeleteLocallyCachedProfiles.
A way to get around this is to run a startup script from group policies, that deletes all locally stores roaming profiles apart fro all users and default user.
Microsoft has developed at tool called delprof.exe that can do this for you. The Windows Server 2003 ressource toolkit can be downloaded here. Then find the tool delprof.exe and add it to your startup script (and the folder for that GPO startup scripts) and run it with a /Q command/parameter.
