This is message in event viewer in most of the computer's on this particular domain.
"The time service has not been able to synchronize the system time for 49152 seconds because none of the time providers has been able to provide a usable time stamp. The system clock is unsynchronized."
I had ran a microsoft update the night before and not restarted the server.
So I reboot the pdc and now all the pc's say this in event viewer.
"The time service is now synchronizing the system time with the time source chXXXXX1.cityhall1.net (ntp.d|172.20.1.169:123->172.20.1.4:123)."
So they should all be right, right well wrong they are all still one hour fast server has correct time pc's in this domain say they are getting time from pdc how come they are still wrong.
Also not having this trouble in any of the other domains.
