first you need to make sure that each machine is listed in
/etc/namedb/domain.db

it should look something like this

pm1 IN A 1111.111.111.1
etc etc etc....

then is /etc/namedb/reverse.db
add something like this

1111.111.111.1 IN PTR pm1.domain.com.
be sure not to forget the period at the end

also add this to you /etc/netstart file

defroute=1111.111.111.1
and so fourth

if you need further help ill be glad to assist
