Creating a

Single-protocol

Network

Synopsis:

This lab will guide you through the assembly and configuration of a simple peer-to-peer network. However, this lab will place special emphasis on network protocol selection. Upon successful completion, you should be able to explain the purpose of a network protocol and why all PC's on a network must share the same protocol in order to communicate.

Materials/Conditions Required:

This lab will require the following:

At least two, Windows 2000 Pro-based PC's each equipped with at least one network interface card. (If you are performing this in the CET lab, these cards are already installed).

A network switch or hub with a free port for each computer. If performed in the CET lab, you will be using the pre-installed classroom switch and not the one on your bench.

A straight-thru (CAT-3 grade or better) twisted-pair network cable terminated with RJ-45 connectors for each computer. If performed in the CET lab, you will not need these cables as they are already installed in the wiring closet.

Procedure to perform the installation:

In this lab, all workstations will communicate using one protocol. First, we will use the NetBEUI protocol, and then TCP/IP. Connectivity between workstations will be tested using the explore facility (found in My Network Places) and/or the command-line ping utility.

1. Boot up with Windows 2000 Server.

2. Verify the uniqueness of the computer name. The computer name should have eight characters. The first six should be pc0000. The last two should be the value of the last two digits of your IP address. To find your IP address, open a command prompt and type ipconfig /all. Look for the words Host name. If you find that your PC name has already been changed to something like pc0000##, you may skip to step 4. Otherwise, go to the next step.

3. Click on Start>>Settings>>Control Panel>>System. Next, click on the Network Identification tab and then click Properties. Enter the new name in the Computer name field. Click OK twice and click Yes to reboot to restart the PC.

Remove Previously Installed Protocols

[pic]

In this section you will take note of what components are installed, and remove any previously installed Protocols.

4. After the PC restarts, right click on the My Network Places desktop icon and select Properties. This should open the Network and Dial up connections window.

5. Right click on Local Area Connections 3 icon and select Properties.

6. This opens the Local Area Connection 3 Properties window. Under the General tab you can see which components have been added and are in use by this particular network interface.

( Open your browser. Do you have access to the internet? ________ Why not? ______. Can you still connect with other hosts locally on your LAN? __________

Proceed to uninstall Internet Protocol (TCP/IP) by single-clicking this entry and then clicking on Uninstall.

A pop-up window will appear asking you to confirm your request. Click Yes to confirm. After about a minute, you will be asked to reboot the PC. Click Yes.

When asked if you want to install a protocol, click No. The reboot process should automatically begin.

After you log back in, you will probably see an error message saying it could not initialize a communication profile. This is because there are no network protocols installed even though the network interface card is still enabled. (Remember you just removed the only protocol that was installed). Click OK to close this pop-up window.

Follow the previous instructions (steps 5 and 6) in order to view the Local Area Connection 3 Properties window. List the installed components below:

Install NetBEUI

In this section we will be installing NetBEUI and checking to see if we have connectivity by browsing the network using explorer.

13. From the Local Area Connection 3 Properties window click on Install...

Select NetBEUI and click OK. Click Close to exit the Local Area Connection 3 Properties window.

Explore the network and list (below) which PCs you are able to view. To explore the network, double-click the My Network Places desktop icon. Double-click the Entire Network icon and then click on entire contents. Double-click the Microsoft Windows Network icon. Double-click the Workgroup icon. List the names of the PC's you see. You can press the F5 key on your keyboard while in this window to refresh the view as more students log on.

17. Uninstall NetBEUI after you have gathered the necessary information above. Follow steps 8-11 but remove NetBEUI instead. Then proceed to step 18.

Install TCP/IP

In this section we will be installing TCP/IP. We will then test connectivity to other PC's by using the command-line ping utility.

After the reboot, verify that all the protocols have been removed.

From the Local Area Connection 3 Properties window, click on Install...

Select Protocol and click Add. List the available protocols below:

|Protocols |

Select Internet Protocol (TCP/IP) and click OK.

Click on Start>>Shutdown and select Restart to reboot your PC.

After logging back in, open up a command prompt to use the ping command.

The syntax for the ping command is ping where the the IP address of the computer you want to ping. (i.e. ping 172.168.211.225 would ping the instructor PC in room 9-211. When you ping a computer, your computer sends a small packet of information over the network to the other computer. The other computer then responds by sending a reply packet back to your computer. If the reply was received by your computer, you will see a message (Reply from...) confirming this. If your computer never got the reply packet, you will see a message regarding the failure. This would be indicative of a network problem.

ping your fellow classmate's IP address. List the IP addresses of the PC's that you were able to ping along with their MAC addresses in the table below. Give some thought as to how you would obtain the MAC address of a device without having to physically walk over to the PC.
