In an AD domain, it's *imperative* that all machines have the same time.
That's why there's already a time sync hierarchy present in an AD domain: domain members will sync with the authenticating DC, DCs will sync with the PDC emulator, and the PDC emulator is the *only* machine where you need to manually set an external time server:
net time /setsntp:
net stop w32time
net start w32time

I need to know how to tell all the computers on the network to get there time from our time server. I need to do this through group policy so I don't have to visit 600 computers. We had a 3 party device we were using for our time sycronization but since we have moved to a routed network this tool no longer works because we are not allowing brodcasting.

Any help on where I can configure this in Group Policy would be really appreciated. I am a group policy newb.

Again: *why* exactly would you want to do change something manually that's by default already setup and configured as it should be?
You're using a domain, so you only need to configure your PDC emulator manually, nothing else (assuming you didn't interfere with the time service before, and that your machines are running W2k or later, but NT4 won't process group policies anyway).

Thanks for the advice oBdA, the reason I asked is becuase the windows time service had been disabled through group policy because we were using a 3rd party tool to get the time for all of our desktops. I wasn't sure where in the group policy editor I could reenable this setting. I managed to find where to make the change.

thanks for the help,
