Microsoft has officially retired its line of Small Business Server
products. Future versions of Small Business Server Essentials will
be included in the Windows Server 2012 family of products under a
new name, Windows Server 2012 Essentials.
On August 1, 2012, TechSoup will also discontinue all Microsoft
Small Business Server products from its catalog, except for Small
Business Server Essentials 2011.
