About This Book Welcome to MCSE Self-Paced Training Kit (Exam 70-293): Planning and Maintaining a Microsoft Windows Server 2003 Network Infrastructure. In this book, you study some of the more advanced applications, protocols, and services included with Windows Server 2003 and learn how to use them to create a network that is both efficient and secure. For many of these applications, protocols, and services, implementing them on a network consists of a good deal more than just running an installation program or configuring a few parameters; many of them require careful planning and continual maintenance once you have completed the initial implementation.
