Hi,

I have an annoying problem I can't seem to find a solution to.  

We have hosted lots of files, mainly PDF's and TIF's on our Intranet within an iFrame.  When users open these files they are presented with this Windows Security warning:

"Do you want to allow files from this website to run on your computer?  you should only run files that come from websites that you trust."

When they click OK the file opens, but I need to prevent the pop-up all together.

I have tried many Group Policies, but none of them seem to work.  The policies include:

Do not preserve zone information in file attachments - enabled
Inclusion list for low file types - enabled - PDF; TIF
Trust logic for file attachments - enabled - preferring the file type
Turn on Enhanced Protected Mode - disabled
Intranet zone template - enabled
Site to zone assignment list - \\fileservername  1   \\domain.local  1  (same for all file servers)
Access data sources across domains - enabled
Allow active content over restricted protocols to access my computer - enabled
Allow file downloads - enabled
Launching applications and files in an iFrame - enabled
Use pop-up blocker - enabled - disable
Intranet sites: include all network paths (UNC's) - enabled
Turn on automatic detection of intranet

There are other policies applied as well, but these are the ones I think are potentially related to the issue.  I have checked that the policies apply to both the users and computers OU's

What am I missing?
