IIS won't serve CF Admin v2021

I have to run CF Admin through IIS instead of the built in TomCat.  I've turned TomCat off in the server.xml file.  I've created a separate site with a single test index.cfm in the root.  I've added the 3 virtual directories: cfscripts, cfide, jakarta.  I've verified that the index.cfm in the root comes up in the browser.

However, /cfide/administrator/index.cfm results in a blank response.  FailedReqLogFile says "The system cannot find the file specified".  No CF errors were caught.

It seems like a permissioning issue, but I've ensured that that all the physical directories that the virtual directories point to have the same permissions as the root folder.

What am I missing?  Any help would be much appreciated.
