MSDCS folder is not updated with new DC

I have a 08 R2 domain with 2 domain controllers. I just installed a new DC a 2012 r2 server. Under DNS the _msdcs.domain.com shows the new server under all the services in there.

However when i go to the domain.com and look in that _msdcs folder the new server is no where to be found.

I am not sure how to get this folder to populate the right way? See picture!
Thanks!

If you have Active Directory integrated DNS zones, wait for replication. If you have primary and secondary zone wait for zone transfer.

_msdscs under the "domain.local" is only delegation for "_msdcs.domain.local".

When you have a separate zone for _msdcs.<yourdomain>, then you shouldn't have a subdomain for _msdcs under the <yourdomain> zone.  Instead you should have a delegation for _msdcs under the <yourdomain> zone, and point it at your DNS servers which have the _msdcs zone.

There's a bit of history here.  Before Server 2003, _msdcs was a subdomain of <yourdomain>.  With Server 2003+, the default for a new domain is to have _msdcs as a separate zone instead of being a subdomain.  However, either configuration will work.  Not sure why you have both.  From what I've seen, when you do have both, the subdomain takes precedence, but maybe 2012 R2 has changed that behavior and prefers the zone.

In any case, I would delete the subdomain, create the delegation (it will show like a grayed-out icon), and then restart the Netlogon service on all the DCs so that they re-register their records in the _mdsdcs zone.

Here's some reading about the _msdcs zone and changing where it is stored.

So is making the delgation even necessary then to the domain.com? Also are all those other folders necessary under domain.com like sites, tcp, and upd?
Thanks!

When you have _msdcs as a zone, then you should have a delegation pointing to it.  The delegation is not needed (and I don't think it can exist) if you have _msdcs as a subdomain.
The rest is needed.

So i left the _msdcs.domain.com zone alone. I deleted the old msdcs folder under my domain.com.
I then setup a delegation under my domain.com zone to _msdcs and i included my 3 DC in there as NS entries. Sound right?
footechCommented:
Yep, that sounds good.

Restarting the Netlogon service on the DCs should make the DCs register all the appropriate SRV records in the _mdscs zone.
