I have been having multiple issues the most recent of which is outlooks inability to receive mail, after a lot of trouble shooting it seems there is a DNS issue, so I ran the DCDiag test and received the following results. Given that I have very little experience managing a server and have no colleagues to turn to can anyone tell me the safest way to identify and remove the specific faults?
I appreciate any advice given.
