Today, Microsoft announced a new server that it's positioning somewhere between its home server product and its server aimed at small businesses. According to Russ Madlener, director of Windows Server Solutions at Microsoft, the new server—called Foundation—will be available in April from Dell, HP, and IBM, and will cost under $1,000. By contrast, if you want the regular small business server, you'll have to spend $1,000 on the software, with the hardware running you another $500 to $2,000, Madlener says.

So what's the difference between this product and its big brother? It supports up to 15 users, instead of 75. Beyond that, it's pretty much the same. You can use it for anything you'd usually use a server for; Madlener says it's most commonly used to run business software applications, though some customers also use it to run a Web site or as centralized file storage.
