Event ID 620 – Trusted Domain Information Modified
Event 620 is logged differently based on the OS. In Win2000, the domain controller logs this event when there are trust additions. It does not log if there are removals, and treats both newly trusted domains and previously trusted domains similarly.
In Win2003, this event is logged whenever an existing trusted domain's properties are modified.
This log data provides the following information:
- Domain Name
- Domain ID
- User Name
- Logon ID
Why does event ID 620 need to be monitored?
Unplanned changes of the Active Directory domain trust settings warrants immediate investigation, and thus, event ID 620 must be monitored.

The advanced Group Policy settings real-time audit reports highlight the elusive change details, and also provide the old and new values of the modified attributes.
Event 620 applies to the following operating systems:
- Windows Server 2000
- Windows 2003 and XP
Corresponding event ID in Windows 2008 and Windows Vista is 4716.
