Dave,

In IIS, on the website in question, go to Properties | Home Directory |
Configuration | App Mappings, and remove the .htr extension from the
list. While you're there, add the mappings ".cfm::$DATA" and
".asp::$DATA" to be processed just like .cfm and .asp files, to
eliminate that other *very* common security hole.
