Study Notes

Identifying and Understanding Issues

Documenting troubleshooting steps is crucial for resolving future similar issues and creating a knowledge base for the help desk.
A ticketing system helps track who is responsible for the problem and its current status.
When troubleshooting a computer that won’t start or a peripheral device that doesn't work, inspect for physical damage, cable wear and dirt, and port damage.
Start by questioning the users about the problem, the computer's status, error messages and unusual conditions.
The problem’s severity is based on the number of users affected.
Determining the time the problem first occurred can provide insight into possible causes.
Troubleshooting often involves an iterative process of establishing a theory, testing it, and if it doesn't work, creating a new theory.
If you cannot resolve the problem, escalate it.
Tier 1 help desk staff perform the classification and testing stages, Tier 2 staff are more experienced, and Tier 3 are IT specialists with more extensive experience.
Avoid making uncontrolled changes to the production system while testing a theory.
Never make changes to the production system before documenting all details of the problem in a ticket system.
Use a web search tool or a product knowledge base to research the symptoms of the problem you’ve identified.

Establishing a Plan of Action

The three typical solutions for any problem are repair, replace, and upgrade.
Test by substitution, using a “known good” duplicate component, to determine if the issue is with the component itself.
Use a Remote Desktop tool to access the system remotely or travel to the user to observe it in operation.
View system, application, or network log files to determine the root cause of the problem.
Monitor other support requests to identify similar problems.

Understanding the Problem

During the understanding stage, develop a theory of the probable cause based on analyzing the symptoms.
Question the obvious issues, like ensuring that the system is set up and being operated correctly.
Use a divide and conquer approach during testing to eliminate categories of problems more quickly.
