In setting up the services site is may be best to use pass through authentication. This is where the current users windows credentials are given to the web interface server. This then saves the client having to authenticate twice. Once we have created the site will have to enable pass-though authentication using the legacy ICACLIENT.ADM file. With that set if we return to out windows 7 client and in the enterprise receiver plug-in set the path though to the services site will will be authenticated using our current windows credentials.
