But a disadvantage of it is that it doesn't do anything to help the
internal name server resolve other internal domains. I'm sure there are
many corporate networks with multiple internal domains running from
multiple *internal* primaries. What is required is a way to tell each
of these primaries that the other internal primaries *are* internal.
Currently, all you can do is send antything that you are not a primary
or secondary for to a forwarder, unless you have patched code to allow
you to configure other *internal* name servers (which fortuantley for
me, I do).
