Microsoft JScript runtime error: RSClientController is undefined

Running Windows Vista 64 bit, Sql Server 2008 on a remote server.  Using ASP.Net and the Report Viewer control on an asp.net page for a local report.  Was also using IIS to host the web site instead of using the web server built into Visual Studio 2008.

Hope this post helps someone else.

–>Place this in the web.config

<add name=”Reserved.ReportViewerWebControl.axd” path=”Reserved.ReportViewerWebControl.axd” verb=”*” type=”Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” resourceType=”Unspecified” preCondition=”integratedMode” />

    I’m not sure how long this code has been out there but thanks man, it saved my bacon!

    I see you don’t use the potential of social websites like FB on your
    site. You can get huge traffic from social sites on autopilot
    using one useful tool, for more info search in google for:

    Alufi’s Social Automation
