This book is designed as your doorway into Internet and gateway administration through Microsoft Proxy Server. If you are new to Proxy Server or gateway administration, this is your ticket to an exciting future. Others who have prior experience with Proxy Server will find that the book adds depth and breadth to that experience. Also, the book provides the knowledge you need to prepare for Microsofts certification exam #70-088, "Implementing and Supporting Microsoft Proxy Server 2.0." The exam is one of the available electives, and it is a crucial step in becoming a Microsoft Certified Systems Engineer. Because Proxy Server is so closely tied to Windows NT Server, it is marvelously scalable and fits into both large and small organizations. It provides the cornerstone on which to build an Internet Web site, or an intranet, while protecting the rest of your network from the outside world. The success of Windows NT Server is reflected in the huge number of software vendors and developers who develop in this environment or who have switched from other environments to Windows NT Server. When you complete this book, you will be at the threshold of a Internet/intranet administration career that can be very fulfilling and challenging. This is a rapidly advancing field that offers ample opportunity for personal growth and for making a contribution to your business or organization. The book is intended to provide you with knowledge that you can apply right away and a sound basis for understanding the changes that you will encounter in the future. It also is intended to give you the hands-on skills you need to be a valued professional in your organization. The book is filled with hands-on projects that cover every aspect of installing and managing Proxy Server. The projects are designed to make what you learn come alive through actually performing the tasks. In addition to the hands-on projects, each chapter offers case projects that put you in the shoes of a consultant who works in all kinds of situations fulfilling the needs of clients. Also, every chapter includes a range of practice questions to help prepare you for the Microsoft certification exam. All of these features are offered to reinforce your learning, so youll feel confident in the knowledge you have gained from each chapter. Chapter 1, "Introduction To Microsoft Proxy Server 2.0," provides a brief history of proxy servers and firewalls, particularly the Microsoft Proxy Server product, as well as explaining its components, hardware, and software requirements. In Chapter 2, "Proxy Server 2.0 Architecture," you are given a detailed look at how the Proxy Server services work together to provide secure access to the Internet. Because of its importance in the Proxy Server environment, Chapter 3, "Understanding TCP/IP," reviews the TCP/IP protocol suite, its history, and its structure. In addition, it discusses IP addressing, subnet masks, and TCP and UDP ports, which are all very important for a successful Proxy Server implementation. Chapter 4, "Internet Information Server Overview," looks at IIS 3.0 and 4.0 and how Proxy Server utilizes their features to provide secure Internet access. After reviewing the important building blocks of a Proxy Server, Chapter 5, "Planning Your Proxy Server Implementation," steps you through the planning process including needs assessment and capacity planning, choosing an Internet connection and ISP, and the physical requirements for your Proxy Server, based on the size of your network and the type of Internet services you are offering. Chapter 6, "Installing Microsoft Proxy Server 2.0," steps you through the installation process including configuring the Local Address Table and configuring your Proxy Server to support multiple protocols. Chapter 7, "Proxy Client Configuration," discusses the configuration process for many types of clients including Windows, Macintosh, and Unix. Chapter 8, "Proxy Server Security," discusses one of the most important aspects of any Proxy Server installation, security. It steps you through the security options available to you and the implementation of each of those options, including packet filtering and logging to track how your Proxy Server is used. In Chapter 9, "Managing And Tuning Proxy Server 2.0," you learn how to administer each of the Proxy services, as well as the Performance Monitor counters that can be used to measure your Proxy Servers performance. Chapter 10, "Internet Access Via Proxy Server," discusses in greater detail the process of connecting your Proxy Server to your ISP and configuring its caching options. In Chapter 11, "Managing Multiple Proxy Servers," you learn about Proxy Server arrays and chains, as well as the different methods for balancing the load among multiple Proxy Servers. In Chapter 12, "Network Address Translation And DNS Issues," we begin to look at some of the issues that arise with Proxy Server installations. Chapter 12 provides a detailed discussion of DNS and WINS and things to watch out for when these systems are used with your Proxy Server. Chapter 13, "Complex Deployment And Configuration Issues," continues the discussion of Proxy Server caveats focusing on reverse hosting and reverse proxying, as well as coexistence with Microsoft Exchange Server 5.5. Chapter 14, "Troubleshooting Proxy Server," discusses the various troubleshooting tasks and tools used in a Proxy Server environment, including the Registry Editor, Performance Monitor, and Event Viewer. Finally, there are three appendixes in this book. Appendix A provides a detailed discussion of the Microsoft Exam Preparation Guide for the Proxy Server 2.0 exam (#70-088). It addresses each of the points in the Exam Preparation Guide and serves as a refresher before you take the exam. Appendix B lists the well-known and registered TCP and UDP ports for use in configuring your Proxy Server. And, lastly, Appendix C discusses the pre-defined WinSock Proxy protocols and how they are used to communicate with the Internet.
