  • Hi Angelo,

    Generally, the issue is caused by the web.config for the Sharepoint site was not correctly modified by the Reporting Services Addin for Sharepoint. This caused the mappings that correctly assigned the "_vti_bin/ReportServer" folder to bring up the Report. Instead we received a 403.14 error because it was trying to browse the folder instead of launching the

    To fix the 403 Forbidden exception we had to modify the web.config file for the Sharepoint site that had the failing report. The following changes needed to be made to it to work:
    1. Go to the Folder C:\inetpub\wwwroot\wss\virtualdirectories\### (all folders)
    2. Do a backup of that web.config file
    3. Make the following modifications:
    Under <Safe Assemblies> put this:
    <SafeControl Assembly="Microsoft.ReportingServices.SharePoint.UI.ServerPages, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.ReportingServices.SharePoint.UI" TypeName="*" Safe="True" />
    <SafeControl Assembly="Microsoft.ReportingServices.SharePoint.UI.WebParts, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.ReportingServices.SharePoint.UI.WebParts" TypeName="*" Safe="True" />

    Under <http handlers> put this:
    <add verb="*" path="_vti_bin/ReportServer" type="Microsoft.ReportingServices.SharePoint.Soap.RSProxyHttpHandler, RSSharePointSoapProxy, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />

    Under <appSettings> put:
    <add key="ReportViewerMessages" value="Microsoft.SharePoint.Portal.Analytics.UI.ReportViewerMessages, Microsoft.SharePoint.Portal, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

    Under </> put this:
    <location path="_vti_bin/ReportServer/ReportServiceAuthentication.asmx">
    <location path="_vti_bin/ReportServer/ReportServiceAuthentication.asmx">
    <allow users="*" />

    Please feel free to ask, if you have any more questions.

  • Hello Jin,

    sorry for the late....

    Only today i was able to test your proposed solution as i had to resolve other issues before.

    I've got a problem when i try to insert into the web.config file the line relative to the section <http handlers>:

    <add verb="*" path="_vti_bin/ReportServer" type="Microsoft.ReportingServices.SharePoint.Soap.RSProxyHttpHandler, RSSharePointSoapProxy, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />

    I think cause the web.config cannot find the specified dll in the gac, infact there isn't.....
    Maybe an Italian 64 bit version of sharpoint got a problem with the rs add in?

    Please help me

    Thanks in advance,

  • Hi Angelo,

    The possible cause may be the one you have mentioned.

    Microsoft SQL Server 2008 Reporting Services Add-in for Microsoft SharePoint Technologies only has two versions X86 and X64. There is no IA64 version.

  • Hi Jinchun, is there any update to your web.config settings for SQL Server 2008 R2?  We are trying to launch reports from a webapp using the ReportViewer control and Reporting Services is in Sharepoint Integration Mode.  We only get the 403 if the Reporting Server is on a different server than Sharpoint Server.  When both are on the same box it works (?)  Thanks, -M

  • Is this correction to any specific version.

    I have not been able to URL access the report server in SharePoint Integrated mode. There appears to be too many corrections to this file, how come? Is this going to be fixed, or future users have to live with it. I am using SharePoint Servr 2010.

    Thanks for contributing to this important thread.

  • I made the suggested changes to the web site Sharepoint-80 on my IIS 7.0. I still get the same error.

    There was no section <http handlers>. There was <httpHandlers/>. I suppose you meant this.

    I did not have to change <appSettings> it was aleady present, the version was instead of as you suggested. however, it did not matter for the errorneous outcome.

    Any suggestions?

    surely, MSFT should have an answer to this.

    I have not made any changes to the wbe.config in the site whose folder is marked, 18050 (this is the CA site)
