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... matthias -- Matthias Apitz / Sisis Informationssysteme GmbH ein Tochterunternehmen der OCLC PICA B.V.
