Recently we have got many issue(s) reported while opening PDF file which are hosted on IIS 7.5 (windows 2008 R2).

Same PDF file use to open up fine when hosted on IIS 6 (windows 2003) box.

To solve this problem you have install hotfix mentioned in KB 979543

Note

  • You may be able to open other PDF documents on this IIS Web site when this issue occurs.
  • This issue does not affect all versions of the Adobe PDF Reader plug-in.

Thanks Mourad for getting this fix out!   Thumbs-up
