I noticed by accident today that I have some unknown webserver listening on port 8000. Opening http://localhost:8000 just returns 404, so I don’t get any hint what exactly is listening there.
netstat -ano to find out, that the process with PID 4 is listening on that port. PID 4 is the System process. Why is my system listening on that port, without me actually starting a server? Or how can I find out what exactly is listening there?
The HTTP response of the server lists
Microsoft-HTTPAPI/2.0 as the server.
As requested by Shadok, here are the entries of TCPView with 8000 as the port. But I doubt it’s useful at all…
