Time sync issue on domain server

I have a Windows 2003 server that is a domain server that all of a sudden the time will jump to 12 fast. I can correct the time and reboot the server - the time is 12 minutes fast again. I have to run the  w32tm /resync command to get it to stay in sync.  This may last a month or maybe just a day or so.

Any ideas on what could cause this issue? This 1 server is the only one in approx. 150 servers in my domain that does this.

Not sure if it has anything to do with it, but this server is running OCS on it.

Thanks!

make sure the Windows Time Service is in auto and running..
The PDC emulator is the primary time source for the domain.

Verify that the time is correct on this DC.

As the first step please try to run

net stop w32time
w32tm /unregister
w32tm /register
net start w32time

Open in new window


and see if everything is working fine.

One question, is it physical or virtual server ?

I doubt that Office Communications Server is the source of this issue.

Have you run w32tm /stripchart /computer:mytimesynchsource to verify that you are getting a jump and not an accumulated drift against the network time source?

Since this is the only one of 150 servers  that exhibits a problem is it configured differently?
