When I attempt to add domain controller to existing domain in server manager I get a message saying that the domain controller for the domain cannot be contacted even though I can ping the IP of the DC. However when I run DFSDiag /TestDCs /DOMAIN:HOMELAB.COM I get an error saying either the specified domain doesn't exist or could not be contacted. I have my DNS settings on the ethernet adapter pointed at the DC IP. Not sure what else to do.... A little help would go a long way.
I didn't find the right solution from the internet.
