Unable to connect publishing custom string handler for output caching. IIS Instance Id is '1957155781', Url is 'http://localhost/ReportServer/ReportService2005.asmx'.

Cause: microsoft.sharepoint.publishing.publishinghttpmodule is trying to cache an unmanaged path.

Fix: Remove this httpmodule from the ./ReportServer virtual directory web.config.

  1. Open the web.config file (D:\Program Files\Microsoft SQL Server\MSSQL.1\Reporting Services\ReportServer\web.config)

  2. Locate the <httpModules> node, if it's not there create it below the <httpHandlers> node.

  3. Add the following <remove name="PublishingHttpModule" />.

Everytime you call a report or the reportserver URL/web service SharePoint tries to turn caching on and it's not a managed path it throws an error, so we need to remove the module in the reportserver.


  1. Thanks! this was the most concise answer to my problem. My MOSS 2007 reports work now!
