I think I have found the culprit.
When I added the most recent DC, I demoted another one, named ORCA.(I am a JAWS fan, what can I say?)
In DCDIAG DNS testing, that server is still listed, and as an error. I looked through the AD DNS and noticed it is still in there in multiple places.
Is it safe/proper to delete all orphaned entries/mentions of that?
From DCDIAG:
DNS server: 10.0.2.1 (orca.domain.com.) 2 test failures on this DNS server This is not a valid DNS server. PTR record query for the 1.0.0.127.in-addr.arpa. failed on the DNS server 10.0.2.1 [Error details: 1460 (Type: Win32 - Description: This operation returned because the timeout period expired.)] Delegation is broken for the domain _msdcs.domain.com. on the DNS server 10.0.2.1 [Error details: 1460 (Type: Win32 - Description: This operation returned because the timeout period expired.) - Delegation is broken for the domain _msdcs.domain.com. on the DNS server 10.0.2.1] -

I have been cleaning AD DNS for a long time and this always happens. Yesterday I did the same for a domain that had this issue for months.

Still on "Server 2003"
I know, I know ... working as fast as I can to get all this upgraded.
Literally almost to the point of being able to upgrade to 2016, but had a few road bumps, and now this road bump.
That doesn't affect functionality on the domain also. I would just make sure there is no other Server 2003 as a DC and upgrade to the lowest DC OS you have.

When you run dcdiag /dns ... do you get errors with the root servers, such as this?
DNS server: 198.41.0.4 (a.root-servers.net.)
2 test failures on this DNS server

Well, except for "G" ... WTH?

BTW:
Turns out the issue was a 1803 thing.
Maybe it is just my environment, but have never had to enable SMB1 before.
Though I did have a couple errors in DNS that I also fixed while I was in there.
And of course the errors above that I posted. Though everything is working perfectly.

SMBv1 Is recently just disabled on all new windows systems

Probably why this is the first time I have seen it.
And assuming any upgrades would just keep it.
-
BTW: those DNS errors were caused by using an older version of DCDIAG, apparently.
Installed newest version and it works like a charm.
-
@jaredbusch I've heard this before, but has anyone actually checked to see if it is disabled.
On 2016 that we just recently deployed it is active by default when configuring it as a file server.
-
I had to go into the Features section of the 1803 client (fresh install) and enable it.
-
It also warned that the share (when trying to connect to the domain) was insecure and SMB1.

It is disabled by default on RS3 of Server 2016 onwards.

Yeah, makes sense since Server 2003 still uses SMBv1.

I hate to be rude, but using 2003 as DCs is asking the company and IT to bend over and just take it. I would seriously question IT and business leadership for making this decision.
EOL was over 4 years ago!!!!!! seroiously WTF is your company doing? and like @JaredBusch said at least dont use it for DCs?

I am not sure if the they have but @BRRABill will explain better. Sometimes reality is different than what we feel needs to be done.

I disagree. The only way it makes any sense to run a product that is 4 years EOL as your DC is if you are paying for support for Microsoft. Anything else is reckless.
