When troubleshooting a network, what's new or what's changed is often a source of trouble. Therefore, when you investigate network woes, be sure to ask yourself, "What's new?" and "What's different?" right away, and then answer in as much detail as possible. While digging up the details, you often uncover the source of the trouble and can determine its solution, all in one swift maneuver.
Tip | Savvy network administrators keep a log of changes and additions to the servers on their networks, so when those key questions are asked, answers are immediately forthcoming. You could do worse than to emulate these professionals! |
