DNS Server IP is 10.0.0.5 and 10.0.0.4
The zone is ActiveDirectory Integrated and exists on two servers.
Ping a known good hostname and receive the correct IP. (Ping VanHalenrocks.mybiz.local replies with 10.0.51.50)
Ping an obviously wrong hostname and receive the IP of the DNS server. (Ping JustinBeiberRocks replies with 10.0.0.5)
I've checked the forwarders list to make sure just the external DNS servers are there. I've checked the names servers. I've never even heard of this behavior before so I am coming to you for help.
