Episode 162: Troubleshooting Methodology — Identifying Problems and Probable Causes

July 20, 2025 · 16 min

Show notes

The foundation of effective troubleshooting is a structured approach. In this episode, we introduce the CompTIA troubleshooting methodology, focusing on the first few steps: identifying the problem, establishing a theory of probable cause, and testing that theory. You'll learn how to ask the right questions, collect information from logs and users, and avoid jumping to conclusions. Proper problem identification prevents wasted time and unnecessary fixes.

We also explore how to classify symptoms, consider recent changes, and determine if a problem is user-specific or system-wide. By the end of the episode, you’ll be able to confidently break down a vague complaint like “the network is slow” into actionable clues that guide your next steps. This episode is about starting smart—because the right first move saves hours of guesswork.
