C. Incorrect: This is not the first step you should take. If it turns out that the networking cable is connected, and after checking the IP addressing information, you may end up using this step later in the troubleshooting process. D. Incorrect: Because the computer was working before the move, you can be pretty sure that TCP/IP is installed.

Windows XP includes a number of advanced networking features more than any other client operating system. Windows XP includes stronger support than ever for the TCP/IP protocol and also includes advanced networking features such as ICS, Win dows Firewall, and Remote Desktop. Windows XP also makes it easier than ever to connect to a local area network or to the Internet. Windows XP Service Pack 2 adds robust, user-friendly tools for connecting to wireless networks. As a DST, you should know how to configure local area network connections, wireless network connections, and dial-up connections in Windows XP. You should understand how TCP/IP connections work and how to troubleshoot them when they do not work. Each device on a TCP/IP network is assigned one or more unique IP addresses that identify it on the network. Computers running Windows XP can be assigned a static (unchanging) IP address or can be configured to obtain IP addresses automatically from a DHCP server on the network. In addition to IP addresses, DHCP servers provide other TCP/IP information, such as subnet masks, default gateways, and DNS server addresses. Should a computer running Windows XP not be able to obtain an address automatically from a DHCP server, the computer will, by default, assign itself an address using Automatic Private IP Addressing (APIPA).

You are working as a DST for a help desk. A user in your company is having problems connecting to the Internet and tells you that he tried to troubleshoot the problem himself using the Properties dialog box for the network connection. You have the user open the command prompt and type ping 127.0.0.1. The user receives an error mes sage. What does this suggest to you A. TCP/IP is not properly installed on the computer.
B. The user should configure 127.0.0.1 as the static IP address for the connection.
C. The computer is having trouble resolving names using the configured DNS servers. D. The 127.0.0.1 address is assigned by the Windows APIPA feature because a DHCP server cannot be located.
One of your customers complains that he can connect to some network resources with no problem, but connections to some resources in remote offices seem particularly slow. You suspect that there may be problems with routing on the network. Which of the following tools is best for examining these issues A. ipconfig B. ping C. pathping D. msconfig
A user complains to you that he cannot connect to any network resources after install ing a new networking card. You open the Command Prompt window on the user s computer and type ipconfig /all. You get the following results: Ethernet adapter Local Area Connection:

One of your customers owns a small business with six computers running Windows XP. The business has a single Internet connection a cable modem connected to one of the computers. The owner configured ICS on the computer connected to the Internet and then restarted the other computers on the network. All computers except one could connect to the Internet. You ask her to type ipconfig at the command prompt of the computer that does not connect, and she gets the following result: Ethernet adapter Local Area Connection:
Connection-specific IP Address. . . . . Subnet Mask . . . . Default Gateway . . DNS . . . . . . Suffix. . . . . . . . . . . . . :
