А что значат вот эти строки:

Domain Controller Diagnosis

Performing initial setup:
Done gathering initial info.

Doing initial required tests

Testing server: Default-First-Site-Name\VIRIAL-SEC
Starting test: Connectivity
The host e78db258-0e49-4d68-ab84-a20fbbb4c66a._msdcs.ad.virial.ru could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name

(e78db258-0e49-4d68-ab84-a20fbbb4c66a._msdcs.ad.virial.ru) couldn't be

resolved, the server name (virial-sec.ad.virial.ru) resolved to the IP

address (192.168.8.3) and was pingable. Check that the IP address is

registered correctly with the DNS server.
......................... VIRIAL-SEC failed test Connectivity

Причем и на основном сервере то же самое:

Причем нашел этот результат dcdiag полугодовой давности - было то же самое.

Это вот e78db258-0e49-4d68-ab84-a20fbbb4c66a._msdcs.ad.virial.ru CNAME запись для второго сервера сервера на нем, а e78db258-0e49-4d68-ab84-a20fbbb4c66a._msdcs.ad.virial.ru тоже CNAME запись в той же зоне на главном сервере.
