I currently have 1 server running Microsoft Server 2003 with roughly 35 employees. I want to add an additional server and have that server run Server 2003 and Exchange 2003. I need to know if I need to purchase licenses for 35 logins to the server and an additional 35 licenses for exchange. Also, instead of using Server 2003 and installing Exchange, i was thinking about installing Microsoft Small Business server 2003 with Exchange built into it. But can Microsoft SBS login to my domain, or does it need to be a standalone server? Any and all help is greatly appreciated. Andy
