  The above class is called in my code behind page_load as:

  if (!Page.IsPostBack)

  {

  // Set the processing mode for the ReportViewer to Remote

  ReportViewer1.ProcessingMode = ProcessingMode.Remote;

  ServerReport serverReport = ReportViewer1.ServerReport;

  ReportViewer1.ServerReport.ReportServerCredentials = new MyReportServerCredentials2("user", "password", "domain");

  // Set the report server URL and report path

  serverReport.ReportServerUrl = new Uri("http://Mydomain/reportserver");

  serverReport.ReportPath = "/correctfolder";

  // Create the sales order number report parameter

  ReportParameter rpDivision = new ReportParameter();

  rpDivision.Name = "Division";

  string rqsDivision = Request.QueryString["Division"];

  rpDivision.Values.Add(rqsDivision);

  // Set the report parameters for the report

  ReportViewer1.ServerReport.SetParameters(

  new ReportParameter[] { rpDivision });

  }

  In my web.config I have:

  I've tried several different solutions, and can't get past this 401 error.
