Query: A must read for IT Professionals.

In the author's own words "this is not meant to be light bedtime reading, but an exploration of the more technical issues of Windows 2000 Server." If you already have a good grasp of basic Windows 2000 Server Administration and want to move up to the next level, start here. There are plenty of walkthroughs, best practices, and real world advice that goes far beyond the "marketing hype" that can be found in much of Microsoft's documentation. The author strikes a good balance between providing excellent technical depth without getting bogged down by it.
