I am installing Exchange Server 2003 on a new Windows 2000 server. The idea is to migrate my Exchange 5.5 mailboxes from the old mail server, which is also a Windows 2000 server, to the new server. When I try to do this using the Migration wizard, I get a message that the server, password or port is wrong. When I use the active directory tool in the deployment tools, it says the source server is not an Exchange 5.5 server. I have tried everything I have read on this site, including changing the LDAP port the 5.5 server uses. Any help or suggestions would be greatly appreciated.
