Nslookup not working for external domain

[Moore, Mark A.]

We are running into a issue where one of our slave servers isn't resolving non-local domain names.  For the two domains hosted on this server, we can resolve any entry. However, if we try to do an nslookup to cnn, google, yahoo, etc. it fails. We have turned off iptables and verified internet connectivity. Below is the error we get. What other areas should we be looking at to troubleshoot?

Thx in advance for any help given.

nslookup www.cnn.com
