Do you have your hints zone setup?
What does named.conf look like?

[amolshastry]

Hi LazyDog
Here is how my named.conf file looks like

//
// named.conf for Red Hat caching-nameserver 
//

options {
    directory "/var/named";
    dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
    /*
     * If there is a firewall between you and nameservers you want
     * to talk to, you might need to uncomment the query-source
     * directive below.  Previous versions of BIND always asked
     * questions using port 53, but BIND 8.1 uses an unprivileged
     * port by default.
     */
     // query-source address * port 53;
        listen-on port 53 {127.0.0.1; 192.168.10.39; };
         // allow-recursion{192.168.10.0/24;};
};

// 
// a caching only nameserver config
// 
controls {
    inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
