| 9.2.2 |  | Using a structured approach to troubleshooting |

| Troubleshooting is a process that allows a user to find problems on a network. There should be an orderly process to troubleshooting based on the networking standards set in place by an administration. Documentation is a very important part of the troubleshooting process. The steps in this model are: Collect all available information and analyze the symptoms of failure Localize the problem to within a single network segment, to a single complete module or unit, or to a single user Isolate the trouble to specific hardware or software within the unit, module, or user’s network account. Locate and correct the specific problem. Verify that the problem has been solved. Figure shows another approach to troubleshooting. Neither of these concepts are the only methods to troubleshooting. However, the orderly process is of the utmost importance in order to keep a network running smoothly and efficiently. Using a structured approach to troubleshooting, every member of a network support team can know what steps each member of the team has completed to solve a problem. If a variety of troubleshooting ideas are tried with no organization or documentation, problem solving is not efficient. Even if a problem is solved in the non-structured environment, it will probably be impossible to replicate the solution for similar problems in the future.
