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, thats it, not extension... nothing, just "SYSTEM". Whats going on here?

I'm afraid to end this process, what do I do?

UPDATE:

I've solved this through a stackoverflow question. Follow this link to find the solution for how to get IIS to stop listening on port 80 for a specified IP address.
