1). Its very important to identify , what the issue is... 2). Let's take an example, suppose one of user is facing issue to connect to an website. To identify the issue correctly at Network level, we check the user LAN configuration & traffic how it is flowing from his machine to that website. 3). Will check the configuration at L2 end as well as Firewall end... 4). If configuration looks good at L2 switch end meaning, correct lan port is assigned as per structure then we will verify the logs at Firewall end... 5). See, something is blocking by any of perimeter firewall...

Troubleshooting complex network issues requires a blend of technical expertise, analytical thinking, and collaborative effort. When faced with intricate network problems, it's essential to systematically diagnose and address each layer, from physical connections to application performance. Leveraging advanced diagnostic tools and techniques can uncover hidden issues that impact network stability and efficiency. However, technology alone isn't enough—effective communication and teamwork play a crucial role in resolving these challenges.

Post identify the issues, Second thing you can do is to Analyse the findings. 1). Meaning that see only that One user affected or any other users facing same issue... 2).
