I found that port 80 is still occupied as long as iis is turned on, even if the iis service is not started. What"s going on?
iis"s website is set up with two ports, neither of which is 80. in addition, iis is not started.
but port 80 is occupied by the system process with pid 4. Why?
are there any other solutions besides shutting down iis?
solution:
Open the registry:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesHTTP
change the actual value of start to 0.

this problem can be caused by installing sqlserver and reopening the iis service.
