Good Morning,
I am the Network Administrator for a small non-profit organization. We ran into an issue a while back that caused me to discover that at least one static DNS record in our organization vanished. Unfortunately, this DNS record belongs to a mission critical server so it caused a few headaches along the way. Once I re-added the DNS entry, I ran dcdiag.exe and found the following.
I've been in the process of decommissioning Server1 and have moved critical services off of it. This issue began after I disconnected it from the network for a few hours to see if any of our devices were soley dependent on it for DNS. Once I
validated that the environment was generally good to go, (although we were seeing some minor latency due to devices trying to hit Server1 before moving onto Server2 for DNS entries) I reconnected it. I've since restarted Server1 and forced replication to see
if that cleared the issue, but I'm still seeing this.
I'd appreciate any assistance you could provide.
Command Line: "dcdiag.exe /v /c /d /e /s:server2"

The following problems were found while verifying various important DN
references. Note, that these problems can be reported because of
latency in replication. So follow up to resolve the following
problems, only if the same problem is reported on all DCs for a given
domain or if the problem persists after replication has had
reasonable time to replicate changes.

This NC (DC=DomainDnsZones,DC=MOF,DC=ORG) is supposed to be replicated
to this server, but has not been replicated yet. This could be because
the replica set changes haven't replicated here yet. If this problem
persists, check replication of the Configuration Partition to this
server.
