Here are the trouble shooting techniques I have used thus far: All of them work when run from the command line of the DNS server its self. The trouble starts when trying to query this DNS server from another machine. So again, locally, DNS queries are working.

DNS server. A quick edit to my local iptables restored everything to
perfect worknig order with or without TCP.
