Turn off Trusted Documents on the network

This policy setting allows you to turn off the trusted documents feature for documents opened from the network. If you enable this policy setting, users will always see security notifications for active content such as macros, ActiveX controls, data connections, etc. for documents opened from the network. If you disable or do not configure this policy setting, the trusted documents feature allows users to always allow active content in documents such as macros, ActiveX controls, data connections, etc. so that users are not prompted the next time they open the documents. Trusted documents are exempt from security notifications.
