In office #1, the "company.com" master zone is updated automatically from
some Windows machines inn DNS1 and in office #2 the same zone is updated
manually in DNS2 by the administrator who shouldn't update (using freeze
and unfreeze) the master zone from office #1. This is the scenario, and we
need that a simple query to DNS1 be responded with any record from both
zones.
Thanks again
