I have a 2008 R2 server with GPO that generates pop-up menus on extensions of GPG , MPG and MPEG files. This GPO is active in encoding servers. options that appear on the gpg files , mpeg , mpg are " encrypt ", " decryption "

Case in point: When you create a file on a server encoding , the context menu appears well on GPG files. But not on mpeg and mpg files. It has already run before but for some reason it does not work ^ ^

If I change the options in the GPO for MPG and MPEG and I put another extension like foo, bar or tata or anything other , it works .... It is as if the system was allergic extensions MPG and MPEG files. Of course , I tested a deletion of the GPO to MPG extension, but it's still the same problem. And I encounter exactly the same problems with the MPEG extension

What is the class associated with the extension is important and could have an impact on the implementation of this gpo ?

Thank you for your future responses ^ ^

Tell us what GPO you're doing this with and what settings it's using. – MDMarra Dec 12 '13 at 13:44
File extensions call scripts that allow encryption / unlocking files with MPG, MPEG or GPG extensions. Concrete example: - In gpmc.msc> I create a file extension "gpg", I choose the associated class and then I choose what will appear in my context menu> "encryption" "unlocking" So from the client or the GPO is applied when I right-click on a file with GPG for example, I see the options "encryption" "unlocking". But on files with extensions MPG or MPEG, I do not see these options! Hoping to have been a little more clear ^ ^ – user201680 Dec 12 '13 at 13:57
Can you be more specific? I haven't seen this gp setting before. – Zoredache Dec 12 '13 at 16:33
This parameter can be found at: Computer Configuration> Parameter Control Panel> Folder Options Then on the right window, you can add extensions to files of any type That's why you ask? – user201680 Dec 12 '13 at 17:48
Yes, that is what I was curious about. I have never noticed that policy function before. – Zoredache Dec 12 '13 at 18:30
