A Day in the Life of a Computer Support Technician


Part One: Troubleshooting a Connection Problem


Chris works for a large corporation that has several branch offices in the city. Operating as a certified computer support technician, he must roam among the branch offices, solving computer and network problems as they arise.


Chris receives a call that one of the remote offices is having network problems. When he arrives at the remote office, Chris is told that the network is down. This office consists of seven computers connected to a router that connects to a cable modem.


Question: Describe the three things that Chris should check first.


Part Two: Troubleshooting Internet Access


Chris solves the problem in the remote office and returns to the corporate office. On Chris’s return, a coworker named Brian cannot access the internet. He tells Chris that the connection was working fine before lunch.


Question: Reorder the following actions in the appropriate sequence for fixing the problem. Then, provide a brief description of the purpose of each action.


1.     Reboot the user’s PC.

2.     Power down the DSL or cable modem box.

3.     Check whether other computers on the network have a similar problem.

4.     Release and renew the PC’s IP address.

5.     Power down the router.

6.     Power up the router.

7.     Power up the DSL or cable modem box.


Part Three: Network Drive Mapping


Jennifer is using her new laptop computer for the first time and asks you for help. She cannot connect to her local file server. She is accustomed to seeing the file server as Drive K: in the Windows® Internet Explorer® browser. The file server is named File_Server and the shared folder is named Shared_Files.


Question: What menu in the Windows® Internet Explorer® browser do you use to access the Map Network Drive window? What entry should appear in the folder drop-down list in this window? Explain the function of each option in this window.


Without using a mapped network drive, what can Jennifer enter into the Run dialog box to access this folder?


Part Four: Port Filtering and Forwarding


Mary tells you that she needs to participate in a demo of third-party video conferencing software the company is considering for purchase. The vendor’s technical support staff needs you to open Port 3090 on Mary’s computer so they can access it from the internet for the demo. Even though opening a computer’s port is a security risk, it only needs to be open for one day.


Question: List the steps that you would use to open Port 3090 on Mary’s Windows® XP computer. Explain each step briefly.
