I have a web site that is using a reportviewer control 10.0, and the control exports the reports correctly on the test enviroment, but not on production. On production, the PDF export works, but not Word or Excel.
The web.config has the appropriate settings for the ReportViewerWebControl.axd, and the enviroments are both IIS 6.0.
We are missing some KBs on the production server, but I don't think that would be causing any issues.
