XP SP2 blocks PDF files

[marcalans]

Ever since installing SP2 over Win XP Pro I can no longer
open locally-stored PDF files in my browser. For example,
if I create an HTML document and link to a PDF file on my
hard drive, it will not open and instead I get a security
warning and an image placeholder that displays in the
upper left corner. This occurs even though I select the
option to "allow blocked content" when prompted by the
Information Bar.

What's strange is that SP2 does allow me to launch Acrobat
and open PDF files across the Internet, but not those
stored locally on my hard drive.

A solution would be greatly appreciated.

Hi

Add the "Mark of the Web" to your html files and see if that
helps:

*Important*, 'Mark of the Web' is very picky about placement/spaces/
lengths:

Mark of the Web is also described in the chapter "Internet Explorer
Local Machine Zone Lockdown" in document 05_CIF_Browsing.doc

05_CIF_Browsing.doc ("Changes to Functionality in Microsoft Windows XP
Service Pack 2, Part 5: Enhanced Browsing Security") can be downloaded
from here:

If that doesn't work for you, the clients need to lower their
security level on the computers:
