How can I configure two independent DNS Servers

The internal server should never be advertised externally.  All
internal machines should resolve from it.  It should "forward" any
queries it cannot resolve out to the Internet, possibly via your
external name server.

Externally, advertise the external server.  It will receive and pass on
queries from the internal name server; but none of them will be for the
"shared" domain.  ;-)  It will also answer any external queries on the
"shared" domain, though.

You aren't the author of the same name, are you?  ;-)
