Why when I access an aspx (e.g., http://www.example.com/foo.aspx - not the real site) through IE6 would I get a 404 Error (i.e., \"The page cannot be found\") in IIS6
The site is pointing to a different directory where the page is not.
It could be permissions, however I would think you would get an access error instead.
I'm assuming you are running IIS.
