What do you do if your network goes down and you're the only one to fix it?

1 Initial Check

Begin by verifying the scope of the problem. Check if the issue is isolated to one workstation or if it's widespread. Use command-line tools like ping or tracert to test connectivity to local and external addresses. Look at the network's physical components, such as routers, switches, and cabling, to ensure they're powered on and functioning. This initial assessment helps narrow down the potential causes and can often reveal quick fixes like rebooting a router or replacing a faulty cable.

3 Plan Action

With the problem identified, develop a plan of action. Prioritize tasks based on the impact and urgency of the issue. If a critical server is down, restoring it should be your top priority. For hardware failures, determine if you have replacements on hand or if you need to implement a temporary workaround. Document your plan, including any configuration changes you intend to make, so you can review and adjust if necessary.

4 Execute Fix

Now, put your plan into action. Execute the necessary repairs or configuration changes methodically. If the fix involves complex changes, proceed with caution and back up current configurations before making any adjustments. After implementing the fix, verify that services are restored by checking connectivity and monitoring network performance. It's crucial to ensure that your solution not only resolves the immediate problem but also doesn't introduce new issues.

5 Test Network

After addressing the issue, rigorously test the network to confirm its stability. Simulate typical user activities and monitor system performance to ensure everything is functioning correctly. This might involve running speed tests, checking application access, and validating that all network resources are available. Adequate testing can prevent a quick fix from turning into a recurring problem, saving you from future headaches.

6 Document Fix

Finally, document every step taken during the troubleshooting and repair process. This documentation should include the nature of the problem, how it was diagnosed, the implemented solution, and any follow-up actions required. Keeping detailed records will not only help in post-mortem analysis but also serve as a valuable reference for similar issues in the future or for training purposes. Good documentation is a hallmark of a seasoned network administrator.
