Scenario
On your Windows computer, Apache does not start. Go to the event viewer and find the event with error:
AH00072: make_sock: could not bind to address [::]: 80
Problem
The problem is that an application is using the same port 80 as your site on Apache. How to find out what this application is?
Open the command prompt (cmd). Type
netstat -ano
You see all open ports on your computer used by applications. Find the line that (in this case) is about port 80. The PID column shows the number of the program that is using your port.
Open task manager, in the tab “Details” through the PID column you will find the program that is using your port.
Solution
You have 2 possibilities: either stop the program or, if you need the program, change the port used by this program, if possible, or the one used by Apache.
If the program you found through the PID is System, it means that Windows itself is blocking the door. Open the services and you need to stop the “World Wide Web Publishing Service” service. You will also have to set the start in manual, if instead it were in Automatic, because otherwise the next day the problem would reoccur.
