dcdiag errors

Question

Hi,

I am getting the below errors on my primary domain controller DC1 while checking dc health. Does it need an authoritative or nor authoritative restore?

C:\>dcdiag /q
Warning: DsGetDcName returned information for \dc1.domain.local, when
we were trying to reach DC2.
SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.

Hi @create share

A DC restore might be a little extreme for a DNS error or is there more background on the issues you have been having with DC2?
