IIS To Handle Missing Coldfusion Template

I would like to set up IIS7.5 to handle missing .cfm templates rather than allow coldfusion to handle it.  In previous verion of IIS, this worked by IIS checking the existance of the CFM file before passing it to the CF handler.  If IIS didn't find the file, it handled it as a missing document, otherwise, IIS forwarded the request to CF.  I can't find where to do that on IIS 7.5.  Here are the instruction for IIS 6:
