Small Business Server may be perfect for your situation. It's like an all in one server for small businesses. Comes with exchange, fax server, sharepoint, web oulook(my favorite), remote desktop gateway plus tons of other stuff, integrates superbly with office 2003(specially with outlook). All of that with a wizard kinda setup. Throw in ISA server and ur off. like curv ball said, lose the Home versions if ur going AD.
