I tend to see this quite a bit. Is this important, and is there a way
to fix it?

Non-authoritative answer:

Thanks,

This is nslookup doing a reverse lookup on the server's IP address that it
is looking at.
You can ignore it or configure a reverse lookup zone and PTR record for it.

Common error, doesn't effect nslookup's functionality. It's just trying to
tell you the *name* of your DNS server by looking in your reverse zone. If
no reverse, create one. If you have a reverse, then make sure there's a PTR
record for 10.2.0.3.
