OVERVIEW
We have a PDC named TPSDC4 that hosts AD, DHCP and DNS services. I have added two new DCs named B2-SV-DC-01 and B2-SV-DC-02 respectively. These new DCs simply have AD and DNS services. The PDC is an older server that has had many configuration issues, and I plant to decommission it as soon as 01 and 02 are no longer having this DNS issue which I will mention.
PROBLEM
After running the DCDIAG /TEST:DNS command on the new DCs, it is returning warnings regarding A records missing. Looking in the DNS I see all the A records listed in the Forward Lookup Zone under our domain (_msdcs, _sites, _tcp, _udp, DomainDnsZones, and ForestDnsZones).
Running DCDIAG on TPSDC4 yields no errors.
LOG DUMP
This is a log dump of the B2-SV-DC-01 server, and the 02 server returns the exact same result.Performing initial setup:
