This book is a task-oriented administrative guide to Windows XP Professional. Its focus is on providing you with the instruction and knowledge required to administer the Windows XP Professional operating system. All that you'll need to be able to follow most of the book's instructions is one computer with adequate hardware resources to support Windows XP Professional. However, to take advantage of this book's coverage of networking, remote access, and Internet coverage, you'll also need access to a local area network that includes other computers running Windows XP Professional as well as a modem and an Internet connection. Even without all these resources, you'll still be able to review these topics and prepare yourself for the time when such resources may be at your disposal.
