I am currently running Microsoft Server 2003 with SQL 2005, Exchange Server 2003, ISA 2004 and SharePoint 2003 on one system/server/box.
I am Looking to deploy Microsoft CRM 3.0. Reading the deployment guide, I tells me that I have to upgrade to Microsoft Small Business Server 2003 Premium. What is the different between Microsoft Server 2003 and SBS? Why do I need to upgrade If I already have all the software needed?
