c# asp.net mvc ใครมีวิธี ทำ multiple authen ( Form & Window) หรือ ดึง Full Computer Name (Domain \\ Username)

 // var dsf  = System.Web.HttpContext.Current.Request.UserHostAddress;
            // string szRemoteAddr = filterContext.HttpContext.Request.UserHostAddress;
            // string szXForwardedFor = filterContext.HttpContext.Request.ServerVariables["X_FORWARDED_FOR"];
            //var fsdfs = (WindowsIdentity)filterContext.HttpContext.User.Identity;

            //string ip = filterContext.HttpContext.Request.UserHostAddress;
            //string hostname = filterContext.HttpContext.Request.UserHostName;
            //string sads = filterContext.HttpContext.Request.ServerVariables["REMOTE_ADDR"];
            //string asd = Dns.GetHostEntry(sads).HostName;

            string computerName = System.Net.Dns.GetHostName();
            System.Net.IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(computerName);
            System.Net.IPAddress[] ipAddress = ipEntry.AddressList;

            computerName = computerName + "|" + ipAddress[0].ToString();

            throw new Exception(computerName);
            return;


            var dsf = filterContext.HttpContext.ApplicationInstance.Server.MachineName;
          // String CurrentUser = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
            var _Client = filterContext.HttpContext.Request.LogonUserIdentity;
            var Domain = _Client.Name.Split('\\');
