They can be, yes. As has already been mentioned, the best solution is to use the standard Windows time synchronization throughout the domain, and have the PDC emulator sync to an external source. IME that protects you from drift pretty well.

I found that the PDC machine time was four minutes off. It looks to have been using its own internal clock, and I guess that was off. I adjusted it, then after a few minutes checked my site's DC and found that it had updated to the correct time, then a bit later my machine had done the same. So presumably all DCs and workstations on the network will by correct soon. -----Original Message----- From: John Hornbuckle [mailto:john.hornbuc...@taylor.k12.fl.us] Sent: Thursday, January 07, 2010 9:37 AM To: NT System Admin Issues Subject: Time I received a complaint from one of my users that the time on her computer is four minutes behind actual time. And she's right--I've noticed myself that all of our computers are four minutes behind. I've never messed with the time features in Windows, so I'm not sure how to correct this. From what I can tell, it client machines update their time from their site's domain controller. Since this is happening at multiple sites, the time on all sites' DCs appears to be four minutes behind. But where do the domain controllers get THEIR time from?
