Disable open file - security warning via Group Policy

Dear Experts,

I have an .exe file that I wish to run at startup for all users. It is currently in the All Users startup folder, however, each time it runs I get the Open File - Security Warning saying it maybe potentially harmful.

Is there a way to disable this via Group Policy, ideally just for this application, i.e. Application.exe and not all .exe files?

Thanks

I would use the Sysinternals streams utility.  http://www.microsoft.com/sysinternals.

You'll run it against your exe (command line)
 streams.exe -accepteula -d <pathtofile>\application.exe

Open in new window


That will remove the zone data from that file only, and the system will no longer provide a warning about it.  As a matter of practice, I always do this with everything I download.

What you can do is to assign DFS share (where your application.exe resides) to intranet zone via GPO. Details are in the link below.

The .exe is in the local all users startup folder not on a DFS share, would this still apply?

Open Properties of the file, and see if there's button "Unblock". If it's there, press it. If not, please post the screenshot of the warning you see.

The related group policy setting is under

User Configuration-> Administrative Templates -> Windows Components -> Attachment Manager -> Do not preserve zone information in file attachments.
