Check the config for you DNS server and see if it needs to bound to an address bind interface = eth0 Or something like that. Then run whatever the cmd is for stopping it(/etc/rc.d/init.d/named stop) And then start it up and see if it's listening with netstat -an

It's kinda big. You're right. It's not listening which seems to be my problem. named is not listd in my services list for me to enable. The server is a slave. It waits for the primary DNS to send it the data. Brent.
