Problem with windows not liking any files named prn

I recently found a problem with windows not liking any files called prn.html, prn.cfm etc etc. If you try and create a file like prn.html then it will say "File already exists".

I initially thought it was a Cold Fusion error as I was getting some bizarre error messages when trying to write prn.html using cffile.

Does anyone know a work around for it?
