I have a piece of software that is not working correctly because something is using port 80 on my system (NT 4). How can I find out *exactly* what is using port 80? This question has been asked and answered previously in this section; I know I can search my host files for what processes are supposed to run on which port, and the port scanner software recommended in previous answers to this question don't help. Maybe I should kill all running processes in my task manager? Help!
