IIS7 WIN 2008 Telerik.Web.UI.WebResource.axd error 500

[Alessandro]

Hi,
I've deployed my website to a Windows Server 2008 R2 wiht IIS7 . The same website on my machine (windows 7 64bit) run perfectly.
My Web.Config is :

 <httpHandlers>
      <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
      <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/>
      <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/>
      <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
      <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false"/>
    </httpHandlers>

<handlers>
      <remove name="ChartImage_axd"/>
      <remove name="Telerik_Web_UI_SpellCheckHandler_axd"/>
      <remove name="Telerik_Web_UI_DialogHandler_aspx"/>
      <remove name="Telerik_RadUploadProgressHandler_ashx"/>
      <remove name="Telerik_Web_UI_WebResource_axd"/>
      <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" />
      <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode"/>
      <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode"/>
      <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode"/>
      <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode"/>
    </handlers>

I also added the application/x-axd to the mime types of the website just to make sure.
The ApplicationPool is running in integrated mode with the administration user.
After executing my page with a Grid e radajaxmanager i'm still getting an error related to the WebResource :

Hello Alessandro,

My suggestion is to inspect the server response in Fiddler and see the exact error. You can also check your server logs for the error which is causing the problem.

More information about the web resources troubleshooting is available in the following article: Web Resources Troubleshooting.

If you need further help, please provide a live URL to the problematic page with steps to reproduce as well as your Fiddler log dump so that we can examine it on our end.

Kind regards,
Rumen
the Telerik team
