apache not starting in windows

I am pulling my hair out. I cannot start my apache server. When I try
to start the server it immediately shuts down.( as a service) I am
using windows XP. Here is the apache error log:
[Sun Mar 04 21:24:25 2007] [notice] Apache/2.2.4 (Win32) configured --

me if you can assist.
Your help is greatly appreciated.
