Reserved.ReportViewerWebControl.axd not found

Some thoughts scribbled down on Monday 08 December 2008 at 04:16 AM

Ran into this issue the other day at work. We were developing some reporting services reports for a client and viewing them through a report viewer control in the intranet site we were developing.

The reports ran fine in the development environment but as soon as it was published to testing the reports behaved strangely. The test box was a Windows 2008 Server Standard Edition with IIS installed and .NET 3.5 SP1.

ReportViewWebControl-not-found

The reports page was reporting a 404 on the following resource "Reserved.ReportViewerWebControl.axd"

This handler was definitely present in the web.config file:

I did the following to resolve this issue.

  1. Install Report Viewer 2008 Redist + SP1
  2. In IIS 7 | Handler Mappings


IIS-Handler-Mapping

  1. Under Actions | Add Managed Handler...
    IIS-Add-managed-handler
    1. Request path: Reserved.ReportViewerWebControl.axd
    2. Type: Microsoft.Reporting.Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
    3. Name: Reserved-ReportViewerWebControl-axd
      IIS-Add-ReportViewer-Handler
  2. Click OK

Now the reports load up fine.

Thanks for your valuable information, it solved my problem and I posted my tips on blog with a reference to your great post. (http://blog.darkthread.net/blogs/darkthreadtw/archive/2009/02/02/reportviewer-2008-on-iis7.aspx)

After testing, I found "2.Type: Microsoft.Reporting.Microsoft.Reporting.WebForms.HttpHandler, ...." should be Microsoft.Reporting.WebForms.HttpHandler, there is redundant "Microsoft.Reporting.Microsoft.Reporting" in your post.

or in web.config <system.webServer><handlers> add this line:

<add name="Reserved-ReportViewerWebControl-axd" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
