Book excerpt: This book is the Windows Server version of the classic TCP/IP Network Administration. Like the book that inspired it, Windows Server 2003 Network Administration provides an overview of the essential TCP/IP protocols, and explains how to properly manage and configure the services based on these protocols. Any skilled network administrator knows that understanding how things work is as important as knowing how things are done. This book is the essential guide to both, containing everything a network administrator needs to exchange information via the Internet, and to build effective reliable networks. This must-read guide is divided into three distinct sections: fundamental concepts, tutorial, and reference. The first three chapters are a basic discussion of the network protocols and services. This discussion provides the fundamental concepts necessary to understand the rest of the book. The remaining chapters provide a how-to tutorial for planning, installing and configuring various important network services. The book concludes with three appendixes that are technical references for various configuration options. Content specifics include how to: Install, configure, and manage a Microsoft DNS and Windows DHCP server Control remote communications with Microsoft RRAS software Protect hosts with Internet Connection Firewalls Configure Internet and Intranet Web services with IIS Design proper security into your network Troubleshoot the network when problems develop After you've turned the final page of Windows Server 2003 Network Administration, you'll not only understand how to network, but also why it needs to be done.
