Microsoft Network Monitor 3.3

Network Monitor 3.3 is a protocol analyzer application that I use to troubleshoot network security and other issues myself. It allows you to capture network traffic, view and analyze network data. This is Microsoft’s quickest release which came 7 months after the previous version 3.2 .
