HHHEEELLLPPP!!!

Hey guys, I'm busy developing a Intranet site for my company, but am a bit stuck. I've noticed on some sites that when you open an Acrobat file it embeds it into Internet Explorer. It looks like a Acrobat file, but opens in IE and then gives you a few Acrobat options on top (like "save as", etc.).

I would like to do the same thing with our ISO documentation but don't have a clue how it's done. Can any of you guys give me some help? I'd really appreciate it.

Thanx
