nslookup returning an odd result for an AD/DND server

I have an AD server on my network that returns two addresses with nslookup. One is correct, the other is google's dns(8.8.8.8).

​

I am help desk, and have brought this up with management a couple of times and they don't seem to care. We have been using LMHost files to point to most servers as well. I am guessing because the DNS is returning incorrect results.

​

1. Is this correct/fine as management says?
2. What should I do next?
