I've been struggling all day to promote a new DC in a branch site.
The main office is on 192.168.44.0/24 with a branch on x.x.45.0/24.
The PDC is located at .44.2 and the remote DC will be located at .45.2
Most of the process completes. Both systems are in the Domain Controllers OU and are members of the Domain Controllers security group. DNS is resolving by name to all systems across a VPN line joining a pair of Hotbrick firewall/router boxes.
Two sites have been created by Subnet. I have tried promoting the DC with and without DNS (normally I prefer to wait on DNS until I have the DC raised and functional since I am running ADI).
The domain and forest are functional level 2008.
I know, this feels like I should be asking about Fabrikam and Contoso doesn't it?
Sorry it's not a multiple choice... I need to find the permissions error/omission.
The operation failed because:
Active Directory Domain Services could not create the NTDS Settings object for this Active Directory Domain Controller CN=NTDS Settings,CN=DC2,CN=Servers,CN=Vistazo,CN=Sites,CN=Configuration,DC=rmstrnglaw,DC=local on the remote AD DC DC1.rmstrnglaw.local. Ensure the provided network credentials have sufficient permissions.
"The RPC server is unavailable."
