After completing this practice, you will be able to configure computers running Windows XP Professional as DNS clients.
To configure a client to use the DNS Service 1. Click Start and then click Control Panel.
2. In the Control Panel window, click Network And Internet Connections. 3. Click Network Connections.
4. Right-click Local Area Connection, and then click Properties. 5. Click Internet Protocol (TCP/IP), and then click Properties.
6. In the Internet Protocol (TCP/IP) Properties dialog box, select Use The Following DNS Server Addresses.
7. In the Preferred DNS Server text box, type the IP address of the primary name server for this client.
If you are on a network, ask your network administrator the IP address of a DNS server you can use and type that address in the Preferred DNS Server text box. If you are not on a network or if you do not have a DNS server on your network, you can type 192.168.1.203 as the Preferred DNS Server IP address.
8. If there is a second name server available for this client, in the Alternate DNS Server text box, type the IP address of the second name server for this client.
If you are on a network, ask your network administrator for the IP address of a second DNS server you can use and type that address in the Alternate DNS Server text box. If you are not on a
network or if you do not have a DNS server on your network, you can type 192.168.1.205 as the Alternate DNS Server IP address.
A client attempts to send its query requests to the preferred name server. If that name server is not responding, the client sends the query request to the alternate name server.
If you are going to configure several computers running Windows XP Professional as DNS clients, configure some of the clients to use the alternate name server as the preferred name server. This reduces the load on the primary server.
9. Click Advanced, and then in the Advanced TCP/IP Settings dialog box, click the DNS tab. 10. Under DNS Server Addresses, In Order Of Use, click Add.
11. If there is a third name server available for this client, in the TCP/IP DNS Server text box, type the IP address of the third available name server for this client.
If you are on a network, ask your network administrator for the IP address of a third DNS server you can use and type that address in the TCP/IP DNS Server text box. If you are not on a network or if you do not have a DNS server on your network, you can type 192.168.1.207 as an additional DNS Server IP address.
12. Click Add to add the third DNS server address and to close the TCP/IP DNS Server dialog box. There are now three addresses in the DNS Server Addresses, In Order Of Use list box.
13. Click OK to close the Advanced TCP/IP Settings dialog box.
14. Click OK to close the Internet Protocol (TCP/IP) Properties dialog box. 15. Click Close to close the Local Connection Properties dialog box.
16. Close the Network Connections window.
Lesson Review
Here are some questions to help you determine whether you have learned enough to move on to the next lesson. If you have difficulty answering these questions, review the material in this lesson before
beginning the next lesson. The answers are in Appendix A, "Questions and Answers." 1. What is a HOSTS file and when would you create one?
2. Which of the following statements about configuring a DNS client are correct? (Choose all answers that are correct.)
a. If you select the Obtain DNS Server Address Automatically option, at least one of the available DNS servers must be configured to broadcast its IP address.
b. If you select the Use The Following DNS Server Addresses, you are limiting your DNS client to being able to use only two DNS servers, the preferred DNS server and the alternate DNS server.
c. To use the Obtain DNS Server Address Automatically option, you must have a DHCP server available on your network.
d. To configure a DNS client, you use Network and Internet Connections, which is located in Control Panel.
3. Which of the following functions do you perform using the Advanced TCP/IP Settings dialog box? (Choose all answers that are correct.)
a. Edit the IP address of a DNS server. b. Delete the IP address of a DNS server.
c. Enter additional IP addresses for other available DNS servers. d. Edit the IP addresses of the DHCP servers on the network.
4. What does selecting the Append These DNS Suffixes (In Order) option do?
Lesson Summary
● For networks without access to a DNS name server, you can manually create a HOSTS file, which provides host-to-IP address and NetBIOS-to-IP name resolution for applications and services.
● In configuring a DNS client in an environment where there are DNS name servers, you can
configure the client to obtain the address of the DNS server automatically from a DHCP server or you can manually enter multiple addresses for DNS servers.
● In the Advanced TCP/IP Settings dialog box, you can configure how suffixes are added to queries.

Lesson 4: Understanding Active
Directory
Most computers running Windows XP Professional will be clients in a Windows 2000 domain. One of the benefits of joining a Windows 2000 domain is the Active Directory service. It is important to understand the overall purpose of a directory service and the role that Active Directory plays in a
Windows 2000 network. In addition, you should know about the key features of Active Directory, which have been designed to provide flexibility and ease of administration.
After this lesson, you will be able to
● Explain the purpose and function of Active Directory Estimated lesson time: 15 minutes
