I deploy a ASP.net MVC 4 web portal on a Windows 2008 R2 Web server. Somes files are on a share on an other machine (Windows 2003 Standard).
When the navigator request images, form authentication redirect request to the logon page.

I checked right for the files, everyone has full control.
The issue is only in IIS.
I did not configure the IIS so I don't understand why it doesn't work.
