Lab 3-1 Installing Visio and running tutorials

Check
out a Visio disk from me.

Start
your computer and log into an administrator account.

Insert
the Visio CD and run the installation.

Lab 3-2 The Star Topology

In this lab you’re going to set up a simple star
physical network using three or four computers in your group.

Get the following:

8
Two or three computers running Windows 2000 or
XP

8
Enable file and print sharing on both computers

8
A small network hub

8
Cabling for each computer

1.

Log off and turn off the computers.

2.

Obtain a hub. Connect each network computer to a hub. You
are not going to connect this hub to one of our routers. We want just a
simple peer to peer network.

3.

Turn the computers back on and log in locally.

4.

Change the computers from working within a domain into a
workgroup. Each computer must have a unique computer name, but the workgroup
names should all be netplus.

5.

In my network places, view entire network. Find the
Netplus workgroup and double click.

6.

What do you see?

7.

Unplug one of the computers. What happens to the light on
the NIC?

8.

What happens to the light on the hub?

9.

What do those lights indicate?

10.

View my network places, entire network. What do you see?

11.

Why?

12.

Reconnect your workstations to the classroom network.

13.

Rejoin the domain as before.

14.

Draw a picture of your network below and label the path of
the data.

Lab 3-3 Building a Daisy Chain

Together you’re going to build a daisy chain network.
A daisy chain is a series of linked devices, one device to the next. It’s
cheap to set up and easy to maintain, but can get wieldy as the network grows.

Get the following:

8
Two or three simple hubs

8
Cables

o
Regular Cables

o
Crossover Cables

o
Don’t have cables? Make them!

8
Three or four computers

8
Throw the computers into a workgroup named Netplus.

1.

Turn everything off.

2.

Connect the computers to the hubs using regular cables.

3.

Connect the hubs to the hubs using crossover cables.

4.

Why use crossover cables to connect hubs?

5.

Make sure you have at least one computer on each hub.

6.

Log into the computers as administrators.

7.

Check in My Network Places in your workgroup. What do you
see?

8.

If any of the computers are not showing up, troubleshoot
until you can see them all.

9.

Draw a picture of your network, indicating the route the
data would take from the first computer to the last computer.

10.

Put everything back the way you found it.

Answer the questions

11.

What type of port connects one hub to another in
daisy-chain?

12.

What type of cable is required for these ports on simple
hubs?

13.

When connecting hubs in a daisy chain on a 10BaseT
network, what is the max number of hubs you may connect?

14.

Why is this?

Lab 3-4 Using Network Monitor

On this lab you’re going to use a Windows 2003 Server
computer (or Windows 2000) to take a peek at some data packets. Windows comes
with some built in and extra programs that you can use to monitor different
types of network performance.

Get the following:

8
A computer running Windows 2003 Server with
Active Directory installed

8
A workstation connected to server’s domain

8
A crossover cable or hub and cables to connect
the two computers together

8
Windows Server 2003 disk

1.

Log onto your server as an administrator.

2.

Open the administrative tools and run Network Monitor. If
it is not installed, you will need to install it.

3.

Select the default network (yours).

4.

Click the capture button and then click star. The program
will start capturing data.

5.

On with workstation computer, log in as administrator.
Double click on my network places. View entire network and locate your
domain.

6.

Find the server and poke around in it. Keep doing this for
about a minute. You may need to share a folder on the server so that you can
save some items into that folder from the workstation. (Make sure the
administrator has those rights.)

7.

Back on the server, click capture then click stop.

8.

Click capture then click Display Captured Data. The
summary window will appear showing information on captured data packets.
Pretty snifty, huh?

9.

Locate and double click on either an SMB (server message
blocks) or SAP (service advertising protocol) entry and a window looking a
little something like this will come up:

10.

In the middle of the pane you will see a line or series of
plus (+) signs. Double click the + sign next to the word Ethernet.
Information about the Ethernet portion of the packet will display.

11.

What is the MAC address of the destination computer in
this packet?

12.

What is the MAC address of the sending computer?

13.

Exit without saving.

Answer the questions

14.

What is the purpose of a checksum?

15.

What type of address identifies the source of data in a
frame?

16.

What part of a data frame is responsible for making sure
that packets are reassembled in their original order after they arrive at their
destination?
