This event is logged for all new trust relationships connecting to this domain.  While the description says "Trusted" this event applies to both trusted and trusting relationships as documented by Trust Information:.

  • Security ID:  The SID of the account.
  • Account Name: The account logon name.
  • Account Domain: The domain or - in the case of local accounts - computer name.
  • Logon ID is a semi-unique (unique between reboots) number that identifies the logon session.  Logon ID allows you to correlate backwards to the logon event (4624) as well as with other events logged during the same logon session.
