This server may have registration disabled due to the multi-homing.

Kevin, I can also suggest to make sure that it's pointing to itself for DNS,
unless of course some reg entries or other configs were altered, such as
with those articles you mentioned.

Also check the basics, zone name, Primary DNS Suffix, Dynamic updates
enabled, etc.

I'm sorry, I don't understand the second part of your post.

Does this say you have an entry point firewall or you have a NAT or you have
a NAT device that has a built in firewall?

If you only have one NIC on the server with mulitple IPs, then they should
both be registering, needless to say may cause problems with the mutliple
addresses. But what is confusing, is that with the one NIC with two totally
separate IP's of different subnets assigned to it, that can cause confusion
with accessing this server when a client queries DNS for an AD service and
it;s subsequent location. This is a KNOWN issue with DC communication and
not recommended to have more than one NIC on a DC.

Things that will keep it from registering:
1. Not pointing to the internal DNS only.
2. File and Print Services disabled
3. Primary DNS Suffix is missing or incorrect and does not match the zone
name.
4. Dynamic updates not enabled
5. IP properties, DNS tab, "register this connection...." is unchecked.
6. As Kevin said, a reg entry disabling registration.
