Paul Thurrott posted a preview on Windows Server 2008 Foundation, anew low-cost version of Windows Server A quote from the article:

Microsoft last week officially announced a product that Windows IT Pro UPDATE readers have known about since the end of 2008: A new low-cost version of Windows Server called Windows Server 2008 Foundation. Foundation Server, as I'll call it, has already been made available to mainstream server makers like Dell, HP, and the like, and will become available with new low-cost hardware in the weeks ahead. (As with Small Business Server, Foundation Server will only be sold with hardware.)
