If you put a bad file name in the url the error message shows the hard drive directory structure.

No script necessary.
Just put any bad file name in a url for an IIS web server 

cgi version:
Fatal error: Unable to open S:\awebsites\websiteman\html\*a.php in Unknown on line 0

isapi version
Warning: Failed opening 'S:\awebsites\websiteman\html\*a.phpi' for inclusion (include_path='') in Unknown on line 0

This is intended behaviour, use error_reporting = off if you do not want this.

Actually error_reporting = off is a bit meaningless.
One should use
display_errors = Off
to avoid displaying errors to the end users.  Assuming you're still interested in knowing what error messages were triggered, you should also use
log_errors = On
