13-38 Chapter 13 Supporting TCP/IP<br />

Lesson 4: Configuring a DNS Client<br />

There are several methods available for configuring TCP/IP name resolution on Windows<br />

XP Professional clients. The method covered in this lesson uses DNS to provide<br />

name resolution. A second method is to use a HOSTS file. For networks without access<br />

to a DNS name server, creating a HOSTS file, which is a manually maintained local file,<br />

can provide host-to-IP address name resolution for applications and services. HOSTS<br />

files can also be used in environments in which name servers are available, but not all<br />

hosts are registered, perhaps because some hosts are only available to a limited number<br />

of clients.<br />

If there is a computer on your network that is running Windows 2000 Server or Windows<br />

Server 2003 and has the DNS Service installed and configured on it, you should<br />

use DNS for name resolution. This lesson shows you how to configure your computer<br />

as a DNS client.<br />

After this lesson, you will be able to<br />

■ Configure DNS server addresses on a computer running Windows XP Professional.<br />

■ Configure DNS query settings.<br />

Estimated lesson time: 25 minutes<br />

How to Configure DNS Server Addresses<br />

Because DNS is a distributed database that is used in TCP/IP networks to translate<br />

computer names to IP addresses, you must first ensure that TCP/IP is enabled on a client<br />

running Windows XP Professional. Internet Protocol (TCP/IP) is enabled by default<br />

during Windows XP Professional installation. After you have confirmed that TCP/IP is<br />

enabled on your client, you are ready to configure your computer as a DNS client.<br />

To configure your computer as a DNS client, use the following steps:<br />

1. Click Start, and then click Control Panel.<br />

2. In the Control Panel window, click Network And Internet Connections.<br />

3. In the Network And Internet Connections window, click Network Connections.<br />

4. Right-click Local Area Connection, and then click Properties.<br />

Windows XP Professional displays the Local Area Connection Properties dialog<br />

box.<br />

5. Click Internet Protocol (TCP/IP), and then click Properties.<br />

Windows XP Professional displays the Internet Protocol (TCP/IP) Properties dialog<br />

box (see Figure 13-13).
