I have a 2008 Server Standard SP2 64bit running AD, DNS and file server roles. I also have a 2nd 2003 r2 box acting as a BDC. If I reboot the 2008 PDC it will come up with an incorrect date and time around 50% of the time. It seems to have been corrected with a "fix me now" from MSFT but it still happens occassionally. Today it rebooted and came up with the incorrect time, I manually set the time and everything was OK for around 8 hours then I rebooted one of my XP workstation and it could not log in. When I checked the server, it was 2 months ahead and at 5:30 on 3/22/11 it showed 7:30 AM on 5/7/11. Is this a bug, a registry issue or incorrect time settings? Any insight will be greatly appreciated.
