There is an online book called TCP/IP Fundamentals for Microsoft Windows available here. This book gives a great overview of concepts and principles, including both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). Perfect for the Midsize Business IT Pro who is starting out, ramping up, or needing to train up some new support technicians. This book is not a discussion of TCP/IP planning, configuration, deployment, management, or application development. For a discussion of TCP/IP planning, configuration, deployment, and management, see the online Help for Windows Server 2003 and the Windows Server 2003 Deployment Kit. For a discussion of how to develop TCP/IP applications using Windows Sockets, see the Microsoft Developer Network. The book can be used as background information when preparing to take the courses and exams for an MCSE certification.
