Event ID 7016 – Completed Security Extension Processing In X Milliseconds – GPO

If you get the following error in the event log:

Source: Microsoft-Windows-GroupPolicy
Event ID: 7016
Completed Security Extension Processing in 265 milliseconds

This is caused by the computer not being able to apply a group policy setting due to the fact that the group policy setting that is being applied, not existing on the computer.

An example of this might be a group policy applying something involving an environmental variable that doesn’t exist on the computer.

In my case, it was a group policy trying to apply a predefined firewall rule that exists on Windows Server 2012 R2 servers, but was called something different on the Windows 7 PC that the policy applied to.

To my knowledge, there is no log to find out which policy contains the setting that causes event 7016 (Completed Security Extension Processing…).
