DNS server but a client.   The client has to have an /etc/resolv.conf to
know what server to use for lookups and what domains to search.   

What is in your /etc/resolv.conf?   How does that compare to any other
Unix/Linux server you have in your mixed environment?

	What does "dig -x X.X.X.X ptr" resolve to?

	What does "dig <name_returned_by_the_first_dig>" resolve to?
