Troubleshooting “The Internets”
Week 5 – Troubleshooting “The Internets”
This week we focus on using the command-line interface to troubleshoot connectivity issues, as well as using it to do basic tasks.
Now it’s time to introduce a new requirement to your project.
· Rats! Rats have eaten through all of the cables in the building and now some computers are not responding properly.
o Fix it!
How do we identify where the connection problem has occurred? Introducing DOS – An important tool for technicians.
As an IT professional you must be able to find and fix connectivity issues using multiple methods.
· Learn from ComputerHope.com some of the simple DOS commands that you will need:
DOS Commands
· For extra help, and to learn how to elevate a prompt watch the video – Basic DOS Commands:
Play Video
· Practice making folders, changing directories, and finding and manipulating files.
o For advanced students – learn to use command redirection and piping.
· Open up a text editor and create a batch file for the newly created network.
o This batch file must do six functions. Examples include greeting the user when he / she logs in, displaying the time and date, automating file or folder creation, and creating a menu for the user to call other applications or batch files.
o When done, save this file with a *.bat extension to indicate to the computer that it is a batch file.
o Next, hit enter and observe it do its thing.
· Observe the computers that have limited connection, we will use the command-line interface to troubleshoot the problem.
o IPCONFIG (/release all) (/renew all)
o TRACERT (google.com)
o PING (127.0.0.1)
o NBTSTAT
· Use these commands to identify problem areas, attempt to ping different “nodes” or “hops” to identify where the “fault” is.
For your task, submit your strategic analysis of your project.
· Prepare a list of recommended troubleshooting steps for the users of your organization so that anyone could follow if you provided it to them over the phone to help them fix their internet connection. Make sure to identify all of the steps in order, and include conditional branching to cover the major possibilities.
