There are two possible causes:
1. You are trying to use a remote share as a virtual directory, then you need to see this Microsoft advisory for the fix. http://support.microsoft.com/kb/320268
2. The files in your virtual directory may be blocked since they come from an outside source (Izenda). Right click on the files in the virtual directory, including the aspx files and the DLL files and click the unblock button as in the picture below.
