[CentOS] DNS in CentOS

Am running Bind 9 in Cent OS 5.1.   I have a DNS server, that:

- DNS server to hosts in lab.company.com - 192.168.17.x
- forwards query to company.com - 10.100.x.x.


1.  FQDN and by-IP-address ping and nslookup is successful.

2.  ping/nslookup by host-name-only --- from any 192.168.17.x hosts to
any 10.100.x.x hosts fail and vice versa.

I have setup the DNS of lab.company.com - to forward query to the DNS
server of 10.100.x.x.hosts through the /etc/named.conf -

options {
        listen-on port 53 {;; };
        forwarders { port 53;

What tools/logs can I check to troubleshoot this?  should I be
configuring this as a forwarder or should I configure my DNS as a
subdomain to the company.com DNS?

pls advise.
