So both cat \\cws333\d$\djgpp\setup.bat and cat z:\\cws333\d$\djgpp\setup.bat work. Even more interesting, cat \:\\cws333\d$\djgpp\setup.bat works. On both Windows 2000 and Windows 95. Some real potential for abuse here :-) This might allow psuedo disks to go to calls that want them but allow the required stuff to still work.
