In my environment, I have a local network running on segment 10.1.1.xxx, and a datacenter, connected via router to router vpn, running on 192.168.1.xxx. I have a active directory server in the datacenter, and one locally. The local server crashed, and I am unable to recover it. This server was my local DNS server, and AD server. I created a new AD server locally, but when I attempt to "Promote to Domain Controller" in Server Manager, it gets an error saying that "an active directory controller for the domain xxx.com could not be contacted".
I have manually created the DNS entries on the new server for machines on both network segments. I don't know how AD looks up the domain, so a dns entry may be missing. Not sure.
Can someone assist please in getting the new server promoted. Or, it there a file that I can restore from the datacenter AD server to get the local server working?
Both servers running W2012R2.
