“This file came from another computer and might be blocked to help protect this computer”

OK, this option is simple to deal with:

  1. Right click the file
  2. Select “Unblock”
  3. Run the Application (*.exe)
blocked_attachment

If you don’t want this option to keep coming up just change the following Group Policy setting:

  1. gpedit.msc
  2. User Configuration > Administrative Templates > Windows Components > Attachment Manager
  3. Enable: Do not preserve zone information in file attachments
gpo_do_not_preserve_zone_information

    Thanks, but on my Windows Server 2003 machine, there is no such Group Policy setting. Under “User Configuration > Administrative Templates > Windows Components” there is no “Attachment Manager”. Have you seen that setting on a Win2003 machine?

    Lars,
    This is within the GPMC on Windows 2003 SP2. I presume that you you have the standard ADM templates loaded?
    Regards,
