That implies the DC is itself misconfigured in its
own client DNS settings.

What DNS servers are configured on the DC NIC?

Are they all holding the Domain zone, or able to fully
resolve that zone?

Which is why it implies a client NIC->IP
problem on the DC unless the DNS server itself
is misconfigured.

No.

Well, yes, but in the sense that almost all AD replication
OR authentiction (logon) problems are really DNS problems.

Practically all of those DNS problems are due to
misconfiguration. And a high percentage of those
are casue by trying to configure "two sets" of DNS
servers on the client NICs (DCs are DNS clients too.)
