ReportViewer control in vs2005

Hi all,

I am creating a custom reports interface based on SQL Server reporting services 2005.

I'm using the reportviewer control in vs2005 to show my server reports. Now, I have an authentication error. I need the control to pass through some custom network credentials ... How would I do this?

I'm trying the following:

VB Code:

ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote
 
                    ReportViewer1.ServerReport.ReportServerCredentials = New System.Net.NetworkCredential("test", "test")
 
                    ReportViewer1.ServerReport.ReportServerUrl = New Uri("Http://REPORTSERVER/Reportserver")
                    ReportViewer1.ServerReport.ReportPath = "/admin/merchant master file"
                    ReportViewer1.ServerReport.Refresh()

But I'm getting the error:

How could I do this?
Thanks
