WinXP and flopping floppies

So, I see myriad posts regarding the issue of WinXP being tempramental about reading floppies, but have yet to find a workable response.

I am admin in a school enviroment where floppies are used extensively by both faculty and students. WinXp appears to have major issues with recognizing floppies formatted in any other machine – and this is causing us a boatload of trouble.

I’ve tested drives, switched drives, switched diskettes, read a diskette in 3 out of 5 systems – then go back to the same systems that read it, only to have it fail, run virus scans, checked CMOS settings, danced in the light of a full moon while shaking the bones of three free range chickens and nada *sigh*.

Are there any known fixes??
Any ideas???
