The report is rendered properly on the local machine but not on the server.

Error:

The Report Viewer Web Control HTTP Handler has not been registered in the application's
web.config file.  Add <add verb="*" path="Reserved.ReportViewerWebControl.axd"
type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms,
Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
to the system.web/httpHandlers section of the web.config file.

Web.Config

<httpHandlers>
      <remove path="*.asmx" verb="*" />

      <add path="*.asmx" verb="*" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
               validate="false" />
              <add path="*_AppService.axd" verb="*" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
               validate="false" />
              <add path="ScriptResource.axd" verb="GET,HEAD" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
               validate="false" />
              <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              validate="false" />
     
      <add verb="*" path="Reserved.ReportViewerWebControl.axd"  type="Microsoft.Reporting.WebForms.HttpHandler,
           Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
       
    </httpHandlers>

Any ideas?

Thanks,

Hi, write the following code into your web.config file

<appSettings>
    <add key="ReportViewerServerConnection" value="MyNamespace.MyRVServerConnectionClass, MyAssembly"/>
</appSettings>

Reporting Services had never been properly configured.
I did 5 uninstalls and re-installs, then called Microsoft.
