OK Experts, believe it or not we still have a NT4 domain controller. Roaming profiles have always worked fine, however they recently stopped working when the XP workstations had SP3 applied to them. The shares are all visible and I can manually open files on the server in the users profile path. The workstation just cant save the roaming profile to the server upon logoff, nor will it read the profile from the server when logging on. I built a new machine with XP SP2 on it, and everything works fine, and then I applied SP3 to it, and the same thing happens. Anyone know what might be happening here and is there a workaround? Thanks.
