I am very new at this, but my company just set up a site to site VPN between our headquarters and a branch office using two Cisco 2801 routers. I have tested the VPN, and I have full connectivity. I can pint all systems on both ends and access file shares.
I shipped out a Windows Server 2003 R2 box to the branch location and promoted it as a domain controller in our existing domain. The promotion seemed to be successful. I added a new subnet and site for the branch office in Acive Directory, and I can see all of our users on the branch office domain controller.
I was looking at the Directory Service logs on my headquarters domain controller, and it seems that the servers are NOT replicating properly. I am getting an Event ID 1925 with the following error:
The attempt to establish a replication link for the following writable directory partition failed.
Source domain controller:
Source domain controller address:
Intersite transport (if any):
This domain controller will be unable to replicate with the source domain controller until this problem is corrected.
Verify if the source domain controller is accessible or network connectivity is available.
1722 The RPC server is unavailable.
I have x'ed out any company information, but I am afraid the longer that I wait we might run into synchronization problems, so your help is greatly appreciated!
Let me know if you need any additional information regarding this.
Thank you very much for all your help!
