You are the desktop administrator for your company. The company’s network consists of a single Active Directory domain. All client computers are Windows XP Professional computers that have manually configured IP addresses.A new user named Marc reports that he cannot connect to the network. All other users can connect to the network. You run IPconfig.exe on Marc’s computer, and you receive the following response. Windows IP Configuration

You want to ensure that Marc can connect to the network. What should you do?
A.
Run the Netstat -n command on Marc’s computer.
B.
Run the Netdiag /test:ipconfig /fix command on Marc’s computer.
C.
Manually configure Marc’s computer so that it has an appropriate IP address and subnet mask.
D.
Disable Automatic Private IP Addressing (APIPA) on Marc’s computer.
Explanation:
Marc’s computer has an APIPA address, an IP address in the 169.254.0.1 through 169.254.255.254 range with a subnet mask of 255.255.0.0. APIPA self-configuration is used by DHCP clients when a DHCP server is unreachable. In this scenario no DCHP server is in use and all clients are supposed to have static IP configuration. We must manually configure the computer with a static IP configuration.
Incorrect Answers
A: -The Netstat -n command identifies computers using IP addresses instead of names. This would not be useful in this scenario.
B: Netdiag is a command-line diagnostic tool that you can use to test network connectivity. However, we already know from the output of the IPCONFIG command that the computer has an incorrect IP configuration. Netdiag would not be able to reveal any interesting information.
D: Disabling APIPA would prevent the computer from getting an APIPA address. It would still not be properly configured since it still would be a DCHP client. It would have no IP configuration.
