Question: Troubleshooting Network Problems Time Required: 1 hour or more Objective: Troubleshoot a variety of network problems created by a partner. Required Tools and Equipment: Net-XX; a share on the network that client computers should be able to open when their computers are in good working order Description: This lab can be done in pairs, with each student creating a problem on his or her partner's computer. A working system should be able to access the Internet and a file share on the local network (set up by the instructor). While troubleshooting, keep a log stating the problem, symptoms, and the layers of the OSI model you test and the final solution to the problem. The following are some problems you can create (but they shouldn't be done in order):

• Set an incorrect static IP address.

• Set an incorrect subnet mask.

• Set an incorrect DNS server.

• Set an incorrect default gateway.

• Disable Client for Microsoft Networks in the network connection's properties.

• Disable the IPv4 protocol in the network connection's properties.

• Disconnect a cable and/or replace a patch cable with a crossover cable.

• Disconnect the switch from the router (if possible).

• Power off the switch (if possible).
