Question:
Network Troubleshooting
You are a network support technician for a college with 4000 users scattered over five locations. A group of users from the downtown location has called your help desk, complaining that they cannot send or receive messages from the Internet, although they can receive messages on the college's internal mail system. List the steps you will take to troubleshoot this problem and describe why each step is necessary. Suppose that your troubleshooting methodology leads you to determine that the problems was caused by a malfunctioning gateway. Suggest ways in which the problem could have been prevented.
