Debugging Apache, My SQL configuration on XAMP

Following are a usual problem reported from Apache/MySQL users

XAMPP, Apache - Error: Apache shutdown unexpectedly
XAMPP, MySQL - Error: MySQL shutdown unexpectedly

And following general error message will give only clue on a probable port issue where the configured port is already in use. Anybody point this cause will usually predict skype may be the culprit because of a default settings on skype to use ports 80/443 in case the one selected is not available.

-----------------------------------------------------------------------------

This may be due to a blocked port, missing dependencies, 

improper privileges, a crash, or a shutdown by another method.

Following are the usually available advises

1. If you are using the latest Skype, go to Tools -> Options -> Advanced -> connection. Disable the       "Use port 80 and 443 for alternatives for incoming connections"

    Sign Out and Close all Skype windows. Try restart your Apache again.

    To find the program running port 80 conflicting with XAMPP, click theNetstat button at       the far-right. You will see a list of programs together with their respective running port           and PID.

2.  Another reason people usually say is DocumentRoot ServerRoot
