I am about to introduce an Exchange 2003 server in to our Forest which is made up of mostly 2003 servers, a few 2000 left. I have the top level domain of .local and several child domains. I want the Exchange server to serve all. Should I add the Exchange server to the top lever domain? Should it be a domain controller? Will I be able to create mailboxes for existing user accounts in the child domains?
Thanks in advance
