Unable to do Virus Updates after Setting Up Roaming Profiles

I've setup a couple of roaming profiles and on each system I've got logging
on to the 2003 Server they can no longer update the Nortons Antivirus. I t
say users access won't allow a file to be accessed.

I've set the local user on each workstationa as adminstrator and this still
is the problem unable to updat the Antivirus. Any ideas or suggestions will
be appreciated.

Thanks,
