I have a client who currently has a 2003 Svr running as a PDC and file/printer server, servicing approx 30 users. We will be adding an exchange server as they are currently running POP mail via OE and Outlook. I do not want to install exchange on the PDC, but rather add a new server for exchange. MY question is: Can I add an SBS box, but not make it the new PDC, that way minimising the setup and not having to re-connect clients to the new DC. Or...do I add another 2003 Svr with exchange and make it a member server? Any help appreciated.
