Computer Networking Technology
Chapter 5 Lab – Troubleshooting Network Connectivity
Part A
This LAB requires a workstation running Windows or UNIX that has the TCP/IP protocol installed. Ideally, the workstation would be connected to a LAN that allows Internet access. In this project, you will view and modify a client’s TCP/IP properties using the ipconfig command.
1. Click the Windows icon and on the “Search” box that immediately follows, type CMD
2. Your command prompt will likely appear as a letter C followed by a colon and then the name of the directory in which you’re currently working. (For instance, you might see a prompt that reads “C:\Documents and Settings\CISUSER 1>.”) Type ipconfig and press Enter to view a summary of your workstation’s TCP/IP properties.
3. On a separate sheet of paper, write down the values of the four items displayed in the output
(or paste them here). ipconfig 4. Next, you’ll issue the same command, but add the /all switch to obtain the complete TCP/IP configuration for your workstation. Type ipconfig /all and then press Enter.
5. Read through the output of the ipconfig /all command. If you are connected to a network that uses DHCP, notice the date and time when your lease was obtained and when it is due to expire. On your paper, write down your machine’s host name and also the MAC address for your workstation’s NIC. (or paste them here).
(or paste them here).
6. Next, type ipconfig /release and press Enter. What message is displayed? What implications do you predict this command will have on connectivity?
There’s no connectivity.
7. Using your screen shot as a reference, attempt to ping the DHCP server and the DNS server. What are the results?_

8. Type ipconfig and press Enter. Note that your adapter has no IP address and no subnet mask. These two parameters are necessary to communicate with TCP/IP.
9. To get an IP address lease again,
