Read an Excerpt
This book is about TCP/IP as it is implemented on Windows 2000 networks. To this end, we will not be looking at a lot of theoretical documents, nor will we be focused on abstract concepts. Rather, we will get down and dirty with Windows 2000, examining the details that will make your network run better, simplify your life as a network administrator or a consultant, and make things easier to troubleshoot. If something does not fit into those objectives, it is left out.
In some respects this book is going to be long anyway. That is because the Windows 2000 implementation of TCP/IP is feature rich. Many new and exciting things have been added in this version of Windows to warrant a full discussion. I have not assumed you are already experienced with TCP/IP; rather, I start from the ground up, not in a pedantic manner (this book is not for dummies or idiots) but by doing a complete and thorough treatment of the subject.
The time to learn Windows 2000 TCP/IP is not when the network is down, but when things are running well. You want to understand the subtleties of the main TCP/IP services before you deploy them onto a live network. We will share many insights with you and hint at possibilities for further exploration. In fact, you will find many new ideas for monitoring and troubleshooting your TCP/IP implementation inside these covers. Some of the areas that will pay the greatest dividends are troubleshooting, optimization, and security concerns, each of which command considerable attention.
In this book, we look at the TCP/IP protocol stack and describe many of the sources of frustration an administrator can experience. We look at howto set things up right, and how to troubleshoot them if you inherited a mess from someone else.
The target audience is network administrators, consultants, system architects, technicians, help desk personnel, and others who support Windows 2000 or Windows NT. The book is also useful for those wishing to do supplemental reading while preparing for their MCSE certifications. It is therefore a moderately detailed book. We make no real assumptions either about knowledge of the protocols or experience with the products, as we will be discussing them. A basic knowledge of TCP/IP, DHCP, DNS, and WINS is helpful, but that is what the book is about, so if you have never set up a DHCP server, don't worry. If you want to know how to implement a TCP/IP network in a Windows 2000 environment, then this book is for you!
Organization of the Book
Part 1. The Basics
In order to understand how TCP/IP works on Windows 2000 networks, you need to know the basics of TCP/IP. In this section we will bring you up to speed on TCP/IP. We begin with those strange numbers, and proceed to look at how TCP/IP talks to machines on the network.
Chapter 1: Introduction to TCP/IP. Here we look at IP addressing. We go into binary numbers, subnet masks, figuring out IP networks, and the whole nine yards.
Chapter 2: The TCP/IP Protocol Suite. In this chapter we look at the way TCP/IP works. We go into the many different protocols that make up the TCP/IP protocol suite.
Chapter 3: IP Routing. In this chapter we look at the way TCP/IP knows how to get from one machine to another. We discuss concepts like subnetworks, subnet masks, and the like. We also look at static routing, dynamic routing, and some of the various routing protocols supported by Windows 2000. We conclude this chapter with a discussion of troubleshooting tools.
Chapter 4: Network Address Translation. In this chapter we look at NAT. We talk about how NAT works, as well as installation and configuration issues. We talk about Internet connection sharing and conclude the section.
Part 2. A Service Approach to TCP/IP
In this part we take a service approach to TCP/IP. We talk about some of the server services one is normally called upon both to deploy and to maintain in a typical Windows 2000 server deployment.
Chapter 5. Internet Protocol Security. In this chapter we look at Internet protocol security. We will talk about configuring and enabling IPSec. We look at configuring IPSec for transport mode and tunnel mode as well as policies and rules. We conclude this chapter with a discussion of managing and monitoring IPSec.
Chapter 6. Certificate Services. In this chapter we look at Certificate Services in Windows 2000. We look at how to install and configure a Certificate Authority, and at the process of issuing and revoking certificates. We consider the role that a CA plays on the network, and see how to integrate the services into the overall IPSec strategy.
Part 3. Implementing TCP/IP Services
In Part 3 we look at the big three services you will have on your network: DHCP, WINS, and DNS.
Chapter 7. Dynamic Host Configuration Protocol. This chapter is loaded with tips, pointers, and recommendations for implementing, maintaining, and configuring DHCP.
Chapter 8. Windows Internet Naming System. Here we look at WINS. We will see how to install, configure, and maintain WINS. We look at some troubleshooting techniques, as well as several disaster recovery scenarios. We also share some secrets learned from years of consulting in the field and troubleshooting literally hundreds of networks.
Chapters 9, 10. Domain Naming System. In these chapters we talk about the biggie for Windows 2000, DNS. We start at the beginning and talk about the strange vocabulary required for understanding DNS. We then go into some of the concepts, and finally explore the unique implementation of DNS as it stands in Windows 2000. These are extremely critical chapters for network administrators working with Windows 2000.
Part 4. Wrapping Up
In this part we put everything together. We take our knowledge of Windows 2000 TCP/IP details and look at several of the most common types of troubleshooting issues.
Chapter 11. Troubleshooting a TCP/IP Network. In this chapter we talk about troubleshooting Windows 2000 TCP/IP networks. We Will look at the three main types of troubleshooting scenarios: connectivity issues, configuration issues, and name resolution issues. For each of these scenarios, we will examine the various tools and utilities we have at our disposal for working with these types of problems. The major utilities we will examine include ping, tracert, nslookup, and pathping. Each of these tools has its own unique switches that can be invoked from the CMD line. By using these tools, we will be able to successfully troubleshoot most Windows 2000 TCP/IP problems.
About the CD-ROM
On the CD-ROM we have copies of the capture files mentioned in the book to allow you to follow along with the examples. These capture files were generated in the lab we set up when we were verifying the procedures outlined in the book. In addition there are sample batch files also referred to in the text along with hints to allow you to obtain the full benefit from them. The batch files are short collections of commands that I use to simplify various aspects of network administration duties.
