Can you *please* provide:
1. An ipconfig /all of your DC in corporate and the DC in the remote site
2. The AD DNS Domain name
3. The zone name in DNS and if updates are set to allow updates
4. Any firewall rules blocking access between locations
5. Is traffic traversing a NAT device?
6. Does the _msdcs zone exist on all DNS servers?
7. Do you have Sites defined in AD?
That will greatly help diagnosing this.
btw- There the PDC and BDC reference is a legacy reference only related to
NT4. There is a "PDC Emulator Role that runs on a DC to emulate a PDC for
some of the NT4 PDC's functionality in backward level client support,
besides time sync and a couple other functions, but that has no bearing on
AD. All AD DCs are replicas and multi-masters. Data can be changed on any of
them and will get replicated to other DCs, unlike NT4, where the only place
anything can be changed was on the PDC.
