Assessment Title

Rule Text

Active content from CDs must be disallowed to run on user machines.

Description

Discussion Text

This policy setting allows you to manage whether users receive a dialog requesting permission for active content on a CD to run. If you enable this policy setting, active content on a CD will run without a prompt. If you disable this policy setting, active content on a CD will always prompt before running. If you do not configure this policy, users can choose whether to be prompted before running active content on a CD.
