We are trying to install MS Exchange 2010 in a new server. But when the setup run a discovery in the network it detect an old installation of MS Exchange 2000 that apparently was migrated to the current MS Exchange 2003 installation. Our MS Ex 2000 server crash a few years ago, the consultant rescued the settings and pass it to a new MS Exch 2000 server. Then we create a new server with MS Exch 2003, but in the exchange manager console appears the new and the Old server. The old server doesn't have any mailbox. This work was made by a different consultant. The question here is: How can we remove any instance of the MS Exch 2000 from the MS Exch 2003 server without corrupting the 2003 installation?
