Apache Conflicts with Skype: Step by Step Solution

Problem:
Apache doesn't start and shows "Busy".

Description:
After installation of WAMP or XAMPP server, sometimes apache doesn't start. But other services like mysql-server or php are running perfectly. But everytime, it is showing "Busy" as warning and doesn't start when apache is commanded to "start".

Reason:
Every program uses a different port number to run on computer. Some port numbers are allocated for a specific program. Port number 80 is default for webservers. Apache is webserver and it uses "80" as default port number. If this port is already being used by another program, then it will show an warning "Busy" and cannot be started when apache is commanded to start.


Solution:
Try to find out the program which is using port number "80" and quit it. Usually "Skype" uses port number 80 as an alternative port. It is possible to make that port available without quitting "Skype".

From skype toolbar, go to Tools > Options > Advanced Settings > Connection. Then un-check Use port 80 and 443 as alternatives for incoming connections.
