DNS not replicating


G

Guest

In my test lab environment, I built two prestine domain controllers for our root domain (which I will be consolidating our 3 child domains into). I upgraded my NT4.0 PDC, and added it as a child domain of the root

So far so good.... user accounts work, trusts are kept, etc

However, I'm having a problem with getting my DNS servers to replicate. I'm using Active Directory-enabled DNS on my root, and Active Directory-enabled DNS on my child domain, but the two DNS servers aren't replicating. They see each other, and I can see the record for my child domain DC (from my root DNS server), but I'm not able to see the Dynamic Records of my clients

I can see the Dynamic update of my clients on my child domain DNS server, but not from my root domain DNS server. I do not have any errors in my event log, and have even forced replication. Still, to no avail....

could someone please help?

However, I'm having a problem with getting my DNS servers to replicate.
I'm using Active Directory-enabled DNS on my root, and Active
Directory-enabled DNS on my child domain, but the two DNS servers aren't
replicating. They see each other, and I can see the record for my child
domain DC (from my root DNS server), but I'm not able to see the Dynamic
Records of my clients.

"See each other?"

This is a common problem -- you cannot use AD-integrated DNS
until AFTER you have regular DNS working correctly and AD
replicating reliably.

If you put DNS in AD which is dependent on DNS which is then
dependent on AD etc -- AD must first work.

Go back to ONE AD-integrated DNS server or a Primary temporarily.
Make sure DYNAMIC is enable.
Set all the others as secondaries to it and do a manual zone transfer.
Set all DCs to point to this DC in their NIC properties (as clients.)
Restart NetLogon on each DC.
Wait for DC replication (or force it)

Run DCDiag and send the output to a text file (on each DC) and
search for FAIL, WARN, ERROR. Fix those.

Check replication with ReplMon or RepAdmin and THEN switch
back to multi-mastered with multiple AD-integrated DNS servers
and set your DCs to the most efficient DNS server(S)

I can see the Dynamic update of my clients on my child domain DNS server,
but not from my root domain DNS server. I do not have any errors in my
event log, and have even forced replication. Still, to no avail.....

Happens all the time -- usually because the DCs were not
set as clients of the internal, dynamic DNS originally but for
whatever reason the AD wasn't replicating.

Almost all AD replication and authentication problems are
actually DNS problems.

When you integrate DNS into a broken (for replication) AD,
you introduce an infinite failure loop.
