    Section 2.4: Troubleshooting


    This section examines procedures for troubleshooting systems. Concepts covered include:

    • A systematic approach to problem solving.

    • Tips for troubleshooting systems.
    A Essentials Objectives:

    • 2.1 Given a scenario, explain the troubleshooting theory

      • Identify the problem

        • Question the user and identify user changes to computer and perform backups before making changes

      • Establish a theory of probable cause (question the obvious)

      • Test the theory to determine cause

        • Once theory is confirmed determine next steps to resolve problem

        • If theory is not confirmed re-establish new theory or escalate

      • Establish a plan of action to resolve the problem and implement the solution

      • Verify full system functionality and if applicable implement preventative measures

      • Document findings, actions and outcomes

    • 2.2 Given a scenario, explain and interpret common hardware and operating system symptoms and their causes

    Lecture Focus Questions:

    • Why is checking the obvious first so important?

    • What place does intuition have in the troubleshooting process?

    • What is escalation and when should you do it?

    • You have identified the most likely cause of a problem and a course of action to correct the problem. When should you not immediately fix the problem?

    • How could user education be a beneficial step in the troubleshooting process?

    • How does good documentation help in the troubleshooting process?
