6424: The installation of this device was allowed, after having previously been forbidden by policy
On this page
Microsoft says "This event occurs rarely, and in some situations may be difficult to reproduce."
Since we are Ultimate IT Security experts we were easily able to generate this event.
This event is generated when a certain combition of settings are configured for auditing. In Local Computer Policy\Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions you will find these four settings (amongst others):
- Prevent installation of removable devices
- Prevent installation of devices using drivers that match these device setup classes
- Prevent installation of devices that match any of these device IDs
- Prevent installation of devices not described by other policy settings
One of these four settings must be configured and enabled in conjunction with the "Allow administrators to override Device Installation Restriction policies" which is found in the same location.
In order to see this event in the Security log, an adminstrator must open Device Manager and attempt to use the "Add hardware wizard" or the "Update Driver wizard" for a device that is specified in one of the previous four settings and also currently attached to the system and listed under "Other devices" in Device Manager.
These events are logged for all devices we tested – not just USB devices.
