I need to open port 80 on one of the computers on my network for a Bank check scanner.
It won't install because it needs port 80 and I can't truly find what port 80 is, all I get is PID 4 is listening to port 80.
If I go to windows firewall and look at all the inbound rules I have Branch Cache listed next to port 80, but it is managed by a system administrator and can't be altered. I have no idea what branch cache is or what program it would be related to.
Any ideas? or a better way to check what is using port 80?
