So something is broken on my AD. I have two servers one being removed and one new one. All services have been moved from Old to new (DNS, DHCP and FSMO Roles) no errors. When both servers are powered on i have no issues, Dcdiag passes no problem. I turned off the old server for a pre-decom check and the new server is reporting that it can not talk to the domain.
DNS is pointed to itself by private ip not loopback. Name resolution works fine. When i try and load Group policy manager it says Directory service is unavailable and i can choose the dc i want to use and when i select the new server the error repeats.
Also getting a DNS error every 5 min that says "The DNS server has encountered a critical error from the Active Directory. "
