Assistance with active directory and file replication errors
Two domain controllers, connected via VPN connection.
All is working great, however we continue to get errors from what I think are DNS related issues.
Did a dcdiag on what we will call the second server (SERVER2) at the remote location.
Server1 is at the main office.
The log below:

Thanks for the reference, nice refresher.
I should have put Intermediate in the experience box.
Regardless, here is another error I am getting. It's related to RPC, however it's all related to the replication, so I think it's one more clue to the issue.
The error:
__________________________
The Windows NT 4.0 or earlier replication checkpoint with the PDC emulator master was unsuccessful.
A full synchronization of the security accounts manager (SAM) database to domain controllers running Windows NT 4.0 and earlier might take place if the PDC emulator master role is transferred to the local domain controller before the next successful checkpoint.
The checkpoint process will be tried again in four hours.
Additional Data
Error value:
1722 The RPC server is unavailable.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
__________________________
It's event 1586, Source NTDS Replication, Category Replication and User - NT Authority/anonyomous logon
Would this give a clue as to why the DNS is giving problems. I will also report that the DNS event log for both servers is showing no errors.

No, we are dealing with two Win2K3 R2 boxes, that's one of the things that is really confusing me!
ASKER
we are connected via VPN connections, can that be an issue?
ASKER
I'm closing this, found it to be ports not opened on firewall in remote access that was blocking the RPC function
here is a start to look at
