On the client what is in /etc/resolv.conf? Is it getting created
by the dhcp client? What dhcp client are you using? dhclient, or
What setings do you have in dhcpd.conf for domain name servers?
If neither of these is helpful, then using tcpdump or wireshark
to look at the packets on the network may give some clues.
