Port 80 is being used by SYSTEM (PID 4), what is that?
iis, netstat, pid, port
Solution
the IP adress is 0.0.0.0, state = LISTENING: means that port 80 is listening to all interfaces (not used)

Problem
I am trying to use port 80 for my application server, but when I perform `netstat -aon` I get: `TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4` When I look up the process in task manager, it shows `PID 4` is `SYSTEM`, that's it. No extension... nothing. Just "`SYSTEM`". What's going on here? I'm afraid to end this process, what do I do?
