611: Removing Trusted Domain

On this page

This event varies depending on the OS.

Win2000

This event gets logged twice (duplicate) by the domain controller. Unlike event 610, an event 620 does not accompany this event.

The DC logs this event for both trusted and trusting domains. There is no way to make a distinction.

If directory service access auditing is turned on, the DC also logs an event 565 (object opened) and 564 (object deleted) where the object service is LSA and the object type is TrustedDomainObject. Object name identifies the 610, 611 and 620

Win2003

Unlike Windows 2000, Windows Server 2003 only logs this event once for each new domain. Although the description says "new *trusted* domain" this event gets logged for both trusted and trusting relationships.

If directory service access auditing is turned on, the DC also logs an event 565 (object opened) and 564 (object deleted) where the object service is LSA and the object type is TrustedDomainObject. Object name identifies the domain.
