We have been using a website that populates a PDF form data with an FDF. We had Adobe Reader 7 installed. After the upgrade from IE6 to IE8 the forms stopped populating. I downgraded back to IE6 and everything went back to working normally.
I re-installed IE8 and tried acrobat Reader 9.4 and even 10.1 and the FDF issue is still there.
I have tried adding the site as a trusted site in IE, and when that didnt work, I tried it as a local intranet site.
I disabled the enhanced security in reader.
This is running on Windows Server 2003 32-Bit Terminal Server.
