Supporting Users and Troubleshooting a Microsoft Windows XP Operating System

1: You are a desktop support technician for your company. A user reports that his Windows XP Professional client computer cannot connect to a file server named Server7. The user is attempting to connect to Server7 by using its name. You are able to use your Windows XP Professional client computer to connect to Server7 by IP address, but not by name.
You discover that Server7 is a UNIX-based server. Server7 runs file-sharing software so that client computers can connect to it. The user’s Windows XP Professional client computer can connect to all Windows-based network resources by name and by IP address.
Other users report the same problem connecting to Server7.
You need to ensure that all computers can connect to Server7 by name.
What should you do?
A.Configure each computer to use mnode for NetBIOS name resolution.
B.Configure the Hosts file on each computer so that it does not have an entry for Server7.
C.Ask an administrator to add Server7 to the database of the network DNS server.
D.Ask an administrator to add Server7 to the database of the network WINS server.
Correct Answers: C

2: You are a desktop support technician for your company.
A user reports that she just installed Windows XP Service Pack 2 (SP2) on her computer that runs Windows XP Home Edition. Since installing SP2, she cannot use her Web-based e-mail application. When she logs on to the Web site, she can see her messages and the main Web page. However, when she attempts to open a message or create a new message, the message windows do not open. The user could use the application before she installed SP2.
What is the most likely cause of the problem?
A.The user exceeded her message quota for this e-mail application.
B.Windows Firewall prevents the e-mail application from working correctly.
C.The Microsoft Internet Explorer pop-up blocker prevents the windows from opening.
D.The Web site is down.
Correct Answers: C

3: You are a desktop support technician for your company. The company uses a VPN server that supports PPTP and L2TP.
A user of a Windows XP Professional portable computer wants to use a VPN to connect to the network over the Internet when she travels. On the user’s computer, you configure a network connection that establishes a VPN connection to the VPN server. You test the connection, and the connection is established.
Several weeks later, you increase security by configuring the VPN server to support only certificate-based L2TP VPNs. The user reports that she is unable to establish a connection to the VPN server. All other users can connect to the VPN server successfully.
You need to ensure that the user can always establish a VPN connection to the VPN server.
What should you do?
A.On the user’s computer, change the type of VPN to L2TP VPN on the Networking tab of the VPN connection.
B.On the user’s computer, select the Use pre-shared key for authentication check box in the IPSec settings of the VPN connection.
C.Instruct the user to import a recent certificate revocation list (CRL) to her computer.
D.Ask an administrator to modify the firewall settings to allow L2TP connections.
Correct Answers: A

4: You are a desktop support technician for your company. A user reports that his Windows XP Professional client computer cannot connect to a file server named FS01. The user’s computer can connect to all other network resources by name.
You are able to connect to FS01 from your computer by using its name. You are also able to ping FS01 by using its IP address from the user’s computer. However, the user’s computer will not connect to FS01 by name.
You need to ensure that the user’s computer can connect to FS01 by name.
What should you do?
A.Configure the user’s computer to use the correct IP addresses of the DNS servers on the network.
B.Edit the Hosts file on the user’s computer and remove the entry for FS01.
C.Configure the user’s computer to use the correct IP address of the default gateway for its local subnet.
D.Use the route command to add a static route from the subnet that contains the user’s computer to the subnet that contains FS01.
Correct Answers: B

6: You are a desktop support technician for your company. The network consists of an Active Directory domain.
A user reports that his Windows XP Professional portable computer cannot connect to any network resources and cannot authenticate to the domain. The computer was able to connect yesterday. No other users are reporting a problem today. The computer’s IP configuration is shown in the exhibit. (Click the Exhibit button.)
You verify that the computer is physically connected to the network and that it can ping its loopback address and its own IP address. The computer can also ping all other IP addresses on the network, but it cannot connect to any network resources by name. An administrator informs you that the DNS and DHCP servers were moved to a different subnet last night.
You need to ensure that the user’s computer can connect to network resources and authenticate to the domain.
What should you do first?
A.Ask an administrator to repair the DHCP server.
B.Configure the user’s computer to obtain DNS server addresses automatically.
C.Instruct the user to run the ipconfig /renew command from a command prompt window.
D.Ask an administrator to authorize the DHCP server in Active Directory.
Correct Answers: B

7: You are a desktop support technician for your company. The company has a main office and several branch offices. The network consists of an Active Directory domain.
A remote user uses a Windows XP Professional portable computer. The user’s user account is a member of the local Administrators group on his computer.
The user connects to the network by dialing in to a remote access server and authenticates to the domain. The user dials in to several different branch offices, depending on where he is located. The user reports that he cannot configure Internet Connection Firewall (ICF) for a new dial-up connection. In the past, he enabled ICF on other dial-up connections that he created.
You need to ensure that the user can enable ICF on new dial-up connections that he creates.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A.Ask an administrator to add the user’s user account to the local Power Users group on the user’s computer.
B.Ask an administrator to modify Group Policy so that the user can modify the configuration of ICF on his computer.
C.Instruct the user to disable Internet Connection Sharing (ICS) Discovery and Control on his computer.
D.Instruct the user to share the new dial-up connection by using Internet Connection Sharing (ICS).
E.Instruct the user to connect to the network and to log on to the domain.

However, the user’s computer is still unable to connect to any network resources. The new TCP/IP configuration is shown in the exhibit. (Click the Exhibit button.)
You confirm that the TCP/IP address of the user’s computer is valid for the subnet that contains the user’s computer. The network does not contain a DHCP server.
You need to ensure that the user’s computer can connect to network resources.
