Ok, I'm following the process for joining an Exchange 2003 box to an existing 5.5 site. No problems. When I go to install Exchange 2003, however, it never prompts for an installation type (i.e. create a new Exchange org or join an existing one). Any ideas? I'm installing Exchange 2003 on a Win2003 SP1 box. Should I remove the SP1 from the OS and try? Help, I'm going nucking futs. . . .
