Have you attempted to do any Windows Update anytime recently? Try to uninstall those updates, especially if you have installed the below updates:

Security Update for Windows XP KB957097
Security Update for Windows XP KB955069
Security Update for Windows XP KB954459

Then re-install them using Windows Update service.
