The 7 Steps of Troubleshooting a Network Problem

Troubleshooting a network problem is a 7-step process that consists of the following:

  1. Identifying the problem, by gathering information, duplicating the problem, questioning users, identifying the symptoms, determining if anything has changed and defining individual problems clearly.

  2. Developing a theory regarding the cause of the problem based on the data that you have collected.

  3. Testing and confirming your theory by using tools that are available to you.

  4. Coming up with a plan of action that addresses the network issue(s) that you have confirmed.

  5. Implementing the solution outlined in your plan, either by yourself or in coordination with others who have the skills required to implement your plan.

  6. Verifying that you have implemented your solution correctly by properly testing it.

  7. Documenting each step of the process, so that you and others will be able to quickly identify and solve similar issues if they occur in the future.
