NSLookup Failure Followed By Success

[GA Admin]

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

set type=mx
somedomain.com

Server: [10.2.0.3]
Address: 10.2.0.3

DNS request timed out.
timeout was 2 seconds.
*** Request to [10.2.0.3] timed-out

somedomain.com

Server: [10.2.0.3]
Address: 10.2.0.3

Non-authoritative answer:
somedomain.com MX preference = 5, mail exchanger =
mail.somedomain.com

mail.somedomain.com internet address = 1.2.3.4
Thanks,
DC

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.
