The simplest way to get friendly urls to work on IIS7 is to use the import rule functionality. You will need to make sure you have

Microsoft URL Rewrite Module for IIS 7 which is free but only available for the latest versions of IIS

Using the following code snippet, paste this into the rewrite rules box and let IIS convert this into the standard IIS formatting.

RewriteCond %{REQUEST_URI} !(^/farcry|^/webtop|^/flex2gateway|^/flashservices|^/cfide)($|/)
RewriteRule ^([^\.]+)$ /index.cfm?furl=/$1&%1 [L,PT,QSA]
