Multiple Servers come up when doing nslookup FQDN

We have a 4 Domain Controllers, 2000, 2003, and 2 2008's.  We are in the process of completely migrating to the 2008's.  I've recently noticed DNS issues here and there.

Today I ran nslookup bridgeport.k12.oh.us  and it returned all of my DC's a couple member servers and a couple 169 addresses.  

We only have 1 DNS server.

How do I fix this?

I would check 2 things.

(1) Look in DNS manager, properties of your zone and see what is listed on the name servers tab

(2) open the DNS manager, click on your zone and take a look at the records that say "(same as parent folder)" and do some cleanup from there.

AWESOME!   I found them.

Which should be same as parent if I only have 1 DNS controller right now?  All DC's or just the DNS?

Make sure you disable any NICs not being used a system. You should only have one NIC enabled on DNS and DCs.

The reason why you had the multiple records was because you had all the NICs enabled this is the actual solution. Just deleting the records would have done nothing at all since they would have just came back since the NICs were enabled.

Removed record and disabled NIC's.  nslookup looks clean now and GP's are now applying
