an Active Directory integrated DNS Zone and must be available

Question

Noticed the following DNS error in when I logged into the server and can't seem to resolve it. FYI this domain has been upgraded multiple times from Server 2000. Perhaps I need to delete the _msdcs zone that's under my domain to recreate it as a new primary zone?

"DNS: Zone _msdcs.sample.domain.com is and active directory integrated DNS zone and must be available"

I ran DCDIAG /TEST:DNS /e /v and it comes back with everything passed. I then opened the DNS management console and under forward lookup zone I only see my domain, not another zone starting with _msdcs.sample.domain.com.

I attempted to create the zone manually and got the following error:

               OSTDC                        PASS PASS PASS PASS PASS PASS n/a

What can I do to resolve this?

Seems like that's how DNS did it back in the day so it's prob ok to leave as but would like to get other opinions.
