HTTP Server Error Message 'make_sock could not bind to address'

Error Message:

Only one usage of each socket address is normally permitted.  : make_sock could not bind to address 0.0.0.0:80 no listening sockets available, shutting down

Unable to open logs

Problem:

Port 80 is listening by some process.

Solution:

Find which one uses the 0.0.0.0:80 port. Just stop it and keep it free. Then start up apache.

1) 'netstat -noa' will give you the PID of the process that reserves your precious port.

2) 'Ctrl-Alt-Del' and your Windows task manager, if you choose View >Select Colums and check PID, will show you which PID is stealing your port. Stop it.

3) Start HTTP server
