It seems the time is a few hours off on the domain controllers.  Does anyone know how to fix the time zone in ntp?

You set the time on the PDC emulator in the forest root to sync with an external or reliable time source and then let the windows time hierarchy take over from there, two good blogs (one by tigermatt from this site and the other from MVP Michael Smith)

Ok, thanks.  I had ntp setup and working for some time but ran a few updates and seems the time is off by a couple of hours.  Can I just reset the clock on the DC?

do you have the daylight savings patch on?  what you want to do is make sure your PDCe in the root is syncing and has the right time, then you can try and resync those other boxes   w32tm /resync /rediscover

I thought it had been working until today.  Which registry edit shows where it syncs again?

I'll be heading out in a bit so if I don't answer that is why, but those blogs are both good reading.

Thanks
