Fix for PDFs failing to download or downloading sporadically

 

Problem: PDFs downloaded from your website do not load on most client machines. Specifically happens with larger PDF files and sporadically happens across browser clients.   

Atmosphere: Windows Server 2008 R2 running IIS7.5

Cause: According to this lengthy forum post, Windows Server 2008 changes the byte order for downloaded files that Adobe reader didn't know how to read.

Solution: Apply the Windows hotfix #KB979543. Reboot required.
