local system

the authentication types in rsreportserver.config <rswindowsnegotiate /> , <rswindowskerberos /> , <rswindowsntlm /> in iis 7, web site has asp.net impersonation , windows authentication enabled, others disabled the database uses windows authentication. have created login called

ntauthority/iusr
