DNS Server responding with the wrong IP address.
We have an three external DNS servers; one primary and two secondary. All records are static for our public websites.
The primary and secondary DNS servers are responding with the wrong IP address for a specific subdomain. I cannot find anyplace where this IP address is listed in that zone. It is a IP address we own. The specific subdomain is delegated to a load balancer for DNS load balancing. If I query the load balancer specifically, the response is correct. Queries to the three DNS servers are incorrect.
I've tried clearing cache, deleting, and recreating the zone from scratch. When I deleted the zone, it still responded with the wrong IP address for the subdomain. I am completely baffled.
The primary DNS server is Windows Server 2008 Standard with only the DNS role installed. The secondary DNS servers are Windows Server 2008 Core.

I am querying the DNS server directly.

I guess in a way, it's kind of like a ghost A record.

DNS
The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
