Some are dc1 (old ops master;pdc em) and some are set to the w2003 dc's. Unfortunately, we've had some cases where the time is off by 2 - 3 minutes. Both W2k DC's are gc and W2k3-dc is also a gc but not the other w2k3 dc. Flat network so all on same subnet.

All DCs sync to the PDCe. SO…everyone should still be in sync, to within milliseconds. Are all of your DCs group catalog servers? Are all on the same subnet?

Right now we are in mixed mode as we have to keep a couple of the W2k DC's running. W2K3-DC (server) is the ops master and pdc emulator. However, I have run into two situations where it seems the old W2K DC (DC1) ops master seems to be causing problems. Case 1: Windows time. It appears most pc's are syncing their clocks to DC1 instead of W2K3-DC. Case 2: GPO's are not applying properly (note we don't have that many and they only apply to specific computers). Usually the error on the pc in question is that it can't contact a domain controllers to get the policy. I'm perplexed over this as I thought that whatever was the Ops Master for the domain was the top-level controller (for want of a better phrase).Your E-mail and More On-the-Go.
