well, first, there are likely many nameserver software
specific funnies here. but, in general, the big steps
are
o run a nameserver on a box on your network, let's
call it N
o that has to be authoritative for at least your
domain
o be sure that the client resolvers on all other
machines point to that box. the BINDism for this
is an /etc/resolv.conf with
nameserver 666.42.7.11
presuming N is at 666.42.7.11
o of course, for any use of the real internet, N
has to provide at least caching service for the
real internet domain name space, which will get
you into the root hints issue to which you allude.
if all your software is BIND, then maybe get more
specific help on the bind-users@isc.org list. otherwise,
while this list is as good as any, you may want to do a
bit more reading first. you are in a very grotty space
with private dns etc.
