A set of simple commands to trace Internet traffic:
First you want to list out all connections by launching Command Prompt. If not sure which flag to use, type netstat --help to list all available commands.
If you type netstat without any additional flags, only active connections will be listed.
Typing netstat with the flag will list out the process ID as well. e.g. netstat -p
I will usually follow up with running the tasklist command to locate which executable the process belongs to.
