Final answer:
The second step in the process of isolating a network problem is to analyze the symptoms, where one examines the gathered information to understand the issue before proceeding to the solution phase.
Step-by-step explanation:
The process of isolating a network problem generally consists of three basic steps. After the first step of identifying the problem, the second step in this process is to analyze the symptoms. This involves examining the information gathered to understand the nature of the issue. It may include checking error messages, considering any recent changes to the network, and looking for patterns that might suggest a cause. This careful analysis is crucial to effectively diagnosing the problem before moving on to step three, which would involve testing potential solutions and implementing a fix.
