Project 01 - Network Communications & Diagnostics

In this laboratory you will review the use of several popular tools for TCP/IP network communications and management. In addition you will use the Remote Desktop Connection utility to gain access to other computers on a network.

Introduction - TCP/IP allows a common structure for network communications between most any type of computer hardware and operating system. Windows 7 provides access to functionality and tools for TCP/IP including:

  • TCP/IP connectivity tools such as clients for HTTP, FTP, TFTP, Telnet, and finger.
  • A Simple Network Management Protocol (SNMP) agent for monitoring performance and use of resources in any TCP/IP network device.
  • All the standard TCP/IP management and diagnostic tools are available including ipconfig, arp, ping, nbtstat, netsh, route, nslookup, tracert, and pathping.
  • Logical and physical multihoming, allowing multiple IP addresses on a single computer for single or multiple network adapters.[1]

arp -a - address resolution protocol - Returns the interface IP address and the physical addressof your computer network card.

ipconfig - can be used to display the network settings currently assigned and given by anetwork; can be used to verify a network connection and to verify the network settings

ipconfig /all - gives a more complete description of the network configuration

nbtstat -a machine_name - lists the machine's name table given the machine_name

nbtstat -A IP_address - lists the machine's name table given the IP_address

netstat - used to list the TCP/IP network connections

nslookupdomain - used to look up the IP address of a domain or host on a network

ping - used to verify if a network data packet is capable of being distributed to an addresswithout errors. The ping utility is commonly used to check for network errors

tracert destination- (trace route) displays the path along the network to the destination

computer, includes time delay between each hop

tracert -h max_hops destination - permits a maximum of max_hops hops in trace

route

Complete the tasks of this project, answer the questions below, remove submit this section of the handout.

Using the ipconfig Utility

This utility displays the IP configuration for your computer.

1. Click Start and type run in the Search Programs and Files textbox, then select Run.

2. Type cmd in the Open textbox of the Run command window and press OK.

3. In the console window type ipconfig at the prompt and press enter.

What is the IP address of your computer? ______

What is the default gateway?______

At the prompt type ipconfig /? and press enter. This will give you a list of the commands options for the ipconfig utility. (Please do not /release or /renew your IP). At the prompt type ipconfig /all and press enter. This gives you a verbose description of your computer's IP configuration.

What is your computers' Host Name?______

Using the ping Utility

The ping utility provides you with basic information about the connectivity of your computer to the rest of the network and the Internet.

Try pinging the following locations and give a typical time delay for each:

172.21.7.20______

Your own machine IPaddress______

Using the nbtstat Utility

NBT stands forNetBIOS over TCP/IP, and the nbtstat command is used to display TCP/IP connection protocol statistics over NBT.

Type nbtstat /? and press enter to view the command options for this utility. Review the command protocols and use this command to find the MAC address of your computer.

Using Remote Desktop Connection Utility

Find and run the Remote Desktop Connection utility under All Programs->Accessories.

Try out the following activities, and for each discuss the results.

(1) Remote desktop into another machine in the laboratory and run some application.

______

______

(2) Remote desktop into two different machines in the laboratory and move a file from one remote machine to the other.

______
