            Try
                Dim rs As New localhost_reportingService.ReportingService2010

    Hi,

    Generally, the 401 error occurs when the user is not authorized to the Report Server. Besides, if the Reporting Services is configured to use Kerberos, however, we didn't register Service Principal Name (SPN) for the account the Reporting Services is running under, this error will occur as well.

    To resolve the issue, you can simply configure the data source to use stored credentials. If you have Kerberos enabled, you can also address the issue by registering SPN for the report server service. For the detailed information, please see:

    If you have any more questions, please feel free to ask.
