Use network tools to analyze these suspicious connectivity issues and rectify RCA of that incident that this activity will never happen again in my network

Network issues can be elusive, but with a methodical approach, you can uncover the root cause. Start by isolating the problem: test different devices and see if it's local to one or widespread. Use tools like ping or tracert to check for packet loss or delays, narrowing down where the disruption occurs. Next, confirm it's not a simple issue like a misconfigured firewall, expired IP lease, or outdated drivers. Check router logs for anomalies, and if all else fails, inspect any recent changes to software or hardware that could’ve impacted the network. Patience and a systematic process are key!

To uncover mysterious network connectivity issues, start by isolating the problem methodically. Begin with basic checks: ensure all cables are securely connected and devices are powered on. Use command-line tools like ping and tracert to test connectivity and pinpoint where failures occur. Examine network hardware, such as routers and switches, for error indicators. Review configuration settings to ensure IP addresses and DNS settings are correct. Utilize network monitoring tools to analyze traffic for anomalies. If issues persist, consider temporarily disabling security software to rule out conflicts. Document each step to create a clear picture of the problem, guiding you to identify the hidden culprit effectively.
