I have this configuration Preinstalled Windwows SBS 2003 DHCP clients witch take their ip from a router. primary DNS => my w2003 server Some uses roaming profiles, some does not. Clients use windows 2000 profesional and some uses windows XP, all services packs are installed., all have updated norton antivirus I create the profile and everything is ok, but 2 or 3 logons after, the user cannot logon, the machine stalls forever in applying user configuration, and there's nothing I can do to make the user to enter. The weird thing is that the pc seems to do something, because the disk appears to be working. All I can do is delete the profile and everything turns back to normal, for a few hours. Anyone with a similar problem?
