Windows 7: Port 80 PID 4 NT Kernal & System processes

Port 80 PID 4 NT Kernal & System processes

Hi there,

I have a question regarding what processes or services run on Port 80. I am trying to run XAMPP Apache virtual web server and Apache fails to start because a system process is listening on port 80. Apache needs to run on port 80. I had "thought" i fixed the error when I ended the service "web deployment agent service" (after realizing it runs on port 80), after doing this, apache started up just fine no problems. I restarted my computer, and sure enough, apache wouldn't run again. typing "netstat -aon" in a command prompt, sure enough again, port 80 was occupied by a process with a PID of 4...again. I open task manager, and the process descript is again, NT kernal and system process. I try ending the process form the task manager, and it will not stop.

I have double checked services.msc and web deployment agent service is deactivated and not running. because of this i am perplexed as to what additional services would use port 80 just after a re boot.

Any input is greatly appreciated on completely freeing up port 80 so the Apache server can run is greatly appreciated.

Thank you for your time
