I'm running RHE 4 AS and I'm trying to create a Domain and DNS server on the same machine. I've included below my DNS Configuration. My machine has two NICs eth0 is connect to my router and eth1 is connect to my internal network. eth1 has an internal IP address of 192.168.20.8/255.255.255.0. My DNS configuration:

named.conf *************************

//
// 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;
};

When I do a "dig" as shown below I do not get an answer for my domain "silsby.local". What's wrong in the above "dns" config that is preventing for getting an answer for my domain?

[root@cscdserver8 ~]# dig silsby.local

put 127.0.0.1 in /etc/resolv.conf as your nameserver. if that still don't work, recheck your config.
