The article on migrating exchange 2000 to a new server running exchange 2003 was excellent. I have one question however. What is the best way to reconfigure the Outlook clients and OWA to use the new server once you have decomissioned the old exchange server? I seen the upgrade once and because the network was small, they went to each individual machine and reconfigured the Outlook clients. I know there has to be a better way. Thanks, Arthur
