I apologize for this off subject. I'm about to install 2003 exchange server and would like to install it on a 2003 server. Problem is I don't have any 2003 server boxes running. I seem to remember that the first 2003 server upgrade in a domain should be (or has to be) a domain controller? Can anyone tell me if I'm making this up or if there is fact behind that? Thanks Nick PS. Anyone know how to share GALs or create a GAL as an address book between trusted domains? Its not the same forest, organization or anything, only trusted.
