Hello,
Please guys if you have time and knowledge, since i can't figure it by myself.
I have a tree domain, with 3 pain DC's , 2 of them also have DNS roles.
Since a few weeks ago I lost the sync between them and my dcdiag is full of problems.
Since the forest is very big (over 100 domains) all this becomes a very big mess in witch I am lost.
So I have 1 and 5 as DNS and 4 as DC
10.242.0.1 - primary dns
10.242.0.5 - 2nd DNS
10.242.0.4 - DC
Following the DCDIAG from main DC
