If the sound does not come from the little pc speaker, it might be a system or program event of some sort. All sorts of things can cause (or allow) selectable wave files to "announce" something has happened. I would go in the Control Panel/Sounds/Sounds (I do not have Win2k) and see if I can identify the exact sound file that is used. (Most versions of Windows allow a preview of the sounds.) After that, I would see which system events used that file. I would re-assign them slowly to a different file until the one in question sounded different. Note that if the sound card is busy, not all system event sounds will be played, so under a "worse case" scenario this might take a while.
