Accessing WebResource.axd

I have an issue with a .NET application and the error has lead me to an IIS issue.  The only answer I found was for IIS6.  There is no Home Directory tab in IIS 7 and I am trying to replicate these steps which were for IIS6...any help would be appreciated.

  Go to Internet Information Services, right-click on the website, and click Properties.
  1.  Go to the Home Directory tab.
  2.  Click the Configuration button.
  3.  Find the .axd file entry and click Edit...
  4.  Make sure it is mapping to c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll
  5.  Also make sure the "Check that the file exists" box is not checked.  The file technically does not exist until .NET calls for it.
