Error: Cannot write class file

[sawedoff]

Trying to run a simple error page after a login, and get this error:
Errors reported by Java compiler: Found 1 semantic error compiling "C:/CFusionMX/

http://wwwroot/WEB-INF/cfclasses/cfLogInError2ecfm1260186647.java":

1. public final class cfLogInError2ecfm1260186647 extends coldfusion.runtime.CFPage{ <-------------------------> *** Error: Cannot write class file "cfLogInError2ecfm1260186647.class" because that name conflicts with the name of the class file "cfloginerror2ecfm1260186647.class" in directory "cfclasses". This is illegal because file names are case-insensitive in this system.

Does anyone know why? or how to cure it?

Thanks.
