Can’t seem to figure out missing glue record – dcdiag /test:dns

Hello,

I'm in the process of decommissioning an old Windows Domain Controller.

On the new server which is at 192.168.214.15 I run dcdiag /test:dns

I get the following

TEST: Delegations (Del)

Delegation information for the zone: ourdomain.lan.

Delegated domain name: _msdcs.ourdomain.lan.

Error: DNS server: 192.168.214.15. IP:<Unavailable>

[Missing glue A record]

[Error details: 9714 (Type: Win32 – Description: DNS name does not exist.)]

I substituted ourdomain.lan for our domain name but it has the right extension and name.

If I open DNS – server name, forward look up zones, _mscds.oudomain.lan I don't see an issue but I might be missing the obvious.

If I right click and go to name servers, it lists the two correct domain controllers. (the old one is gone)

The SOA is the new server

the NS are the two new servers

and the CNAMes are the two new servers

I've scaveged, cleared cache and flushed dns – no joy.
