css - Only some glyphicons showing in IE

Question

Me and my colleague have been trying to solve this problem for awhile and we can not get it to work. Hopefully someone out there is smarter than us and have some good input on this.

When using IE8, IE9 or IE10 to visit websites http://glyphicons.com/ or http://getbootstrap.com/components/ not all the glyphicons are showing (some are showing but others just show as boxes []).

In Chrome all are showing.

EDIT: I should add that this is on computers on our company network. Could there be a setting here that prevents us for show all glyphicons?

EDIT2: I now have suspicions that our Group Policy disables XMLHTTP for all users on network. Therefore, is it possible to encode the halfling font and use it directly in the CSS?

Answer 1

I have found the solution. It was quite simple. Unfortunately I won't be able to use Glyphicons.

IE have a setting to restrict font download. This is enabled by group policy and cannot be changed on standard workstations. I have been able to recreate the same behavior on my own laptop by restricting font download.
