13 Supporting TCP/IP<br />

<strong>Exam</strong> Objectives in this Chapter:<br />

■ Configure and troubleshoot the TCP/IP protocol.<br />

Why This Chapter Matters<br />

A protocol is a set of rules and conventions for sending information over a network.<br />

Microsoft Windows XP Professional relies on the Transmission Control<br />

Protocol/Internet Protocol (TCP/IP) for logon, file, and print services; network<br />

and Internet access; and other common functions. This chapter presents the skills<br />

and knowledge necessary to configure and troubleshoot TCP/IP. The chapter also<br />

discusses Domain Name System (DNS), how Windows XP Professional performs<br />

name resolution, and how to configure a computer running Windows XP Professional<br />

as a DNS client.<br />
