The anderlying problem is that we are three companies, now connected
through VPN tunnels. Each company runs it's own DNS server internaly and
without publicating all its names to Internet. The three DNS are
10.0.1.201 (mine one), xxx.xxx.xxx.xxx and yyy.yyy.yyy.yyy.
Any idea? Yes, in the future we will unify the whole zone, but this is
not a short term option...
