Don't worry about being a DNS clunkhead. Though some on this list will banish you for trying to learn.
The root servers are non-recursive. Otherwords they only answer for what they know. WHat you are asking for is a server to be recursive in its answer to your query. This is what a ISP"s server will do. What OS is your DNS server running ? If its a Unix version, then I could help via the phone if you would like. write me back privately with contact data.
