Testing the Results
After the corrective change has been made to the server, network, or workstation, it is necessary to test the resultsnever assume. This is when you find out if you were right and the remedy you applied actually worked. Don't forget that first impressions can be deceiving, and a fix that seems to work on first inspection might not actually have corrected the problem.
The testing process is not always as easy as it sounds. If you are testing a connectivity problem, it is not difficult to ascertain whether your solution was successful. However, changes made to an application or to databases you are unfamiliar with are much more difficult to test. It might be necessary to have people who are familiar with the database or application run the tests with you in attendance.
