play sound if wrong xp password entered

how would i got about setting up the windows login screen so it will play a sound if someone types in the wrong password?

Can't swear to it, but I think the only sounds you can change are those listed in the Sound section of the Control Panel. I know there is a Logon and Logoff option, but past that, I don't know. You can maybe check some of the tweaks and see if you can find anything there.
