dcdiag errors



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

we were trying to reach DC2.

Hi @createshare-7115

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?

Gary.
