  Are you using a IP address (192.168.1.2) where a hostname is
  expected? NS records point to hosts not IP addresses. SOA MNAME
  should be a hostname.

so i looked and my SOA's were correct with hostnames. but for the hell of it
in my dhcpd.conf file i changed the nameserver option from a hard ip to the
ns hostname. after i did that i asked for some nslookups from the client. it
complained that it could not locate the ns server. i noticed that ns server
ip address reported by the client was WRONG. two numbers were transposed. i
fixed them in the zone file and VOILA, IT WORKS.

having put the name server's hard ip in the dhcpd.conf. the client would
never have let me know that there was something wrong its record in the zone
file. and i would have NEVER seen it without your help.
