Hi Winston,

The httphandler registration is different for IIS6 and IIS7. The one you have shown is for IIS7, still you might need the one for IIS6. We recommend removing the chart httphandler registration completely and using the link in the VisualStudio smart tag (check the second image in this help topic) -- it will register the httphandler correctly for both IIS6 and IIS7.

Another possible reason is webfarm -- RadChart will work in web farm environment under certain conditions. It would be an issue if the page is served and therefore the chart image is generated by one machine and the next request for the image itself is served by another machine. Then this second machine will not be able to find the image. You will need to be sure that the chart httphandler is served by the same machine, which served the page.

All the best,
