nslookup: no response, captured 3 "server failure" packets

Ok, I'm running Fedora Core 3 on an HP SMP box with a built-in (motherboard) ethernet adapter and 2 CPUs. I tried to set up a DNS server on my local LAN (No internet connection), setting up zones for root, .com. , foobar.com., localdomain. 0.0.127.in-addr.arpa., and 0.168.192.in-addr.arpa. When I scan my ports with nmap, port 53 is open. I attempted a DNS query with nslookup, and after about 5 seconds it returned an error something like "no response from server." A packet capture on lo with tethereal showed 5 IN A requests and 3 IN A server failure responses. The server is running (ps -A|grep named).

What is going on??

Is there anything in the logfile?

Code:

grep named /var/log/messages

What happens when you do a local DNS query?

Code:

dig -x 127.0.0.1
dig localhost
dig foo.bar

What does your BIND config look like?

Code:

cat /etc/named.conf

I am at school right now, but I remember grepping /var/log/messages and it showed that named had received the response and replied to it. dig and host gave the same response as nslookup, as did ping. When I get home I will post my named.conf and zone database files.

I just installed Fedora Core 4 on the server, wiping out the config files. Whoops.
