As far as I remember from AD, all DC and stations synchronise by default to the DC with the PDC emulator role(and this setup is cascade with child domain). You can change the time source with a registry entry but clearly, something is offsetting the PDC clock... Is it a physical or VM server? If a VM, make sure you are not trying to sync the VM to the supervisor you are using (default mode). If not, the offset value of the PDC is completely wrong. The offset value is use by NTP to correct the server drift between NTP query to the external clock. Reset/delete the offset and let the system recalculate it

Are they configured to sync with the PDC via GPO? Have you restarted the W32Time service on the remaining (if any) DC's, and resync'ed (w32tm /resync)? I believe they should sync with the PDC this way, and the clients will sync with their DC. Tiago Ribeiro S. A.
