I'm just upload my new and first mvc3 site on Winhost. Everything goes ok except pages which are for admin eyes only, so they are decorated with [Authorize(Roles = "Admin")] attribute. Even I am logged in with admin credentials and appropriate user group I cannot see this page, getting 404 error (HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.) On my dev machine everything works. Since I'm new on Winhost I would like details steps which are required to make this work. Thank you.
