Adobe acrobat and reader issues

Hi all,

I have a terminal server that has Adobe acrobat and reader installed on it. Acrobat itself is only needed by 2 users. Everyone else needs to use reader.

Unfortunately, Acrobat makes itself the default for opening PDF files. Is there to make reader the default program instead of acrobat proper with out having to change the file extension settings for every user under Tools->Folder Options->File Types?
