Boot Camp Issues

I switched my start up to boot camp/windows. As I booted and loaded Windows it says that boot camp has encountered a problem and doesn't load.

I finally figured out how to get back to the mac side, but what is wrong with my boot camp? What can i do to fix it?

Thanks in advance for your help!

 

Been to busy and have just been living with the problem. To answer your questions:

XP Pro
iMac 27 inch
Latest version of Boot Camp/operating system.

Also to add: Windows continues to operate fine, I just get the error notice and i lose the icon in the lower right allowing me to reboot into OS X.
