Event ID: 551 Source: Security

User initiated logoff:
User Name: <user name>
Domain: <domain>
Logon ID: <ID>.
As per Microsoft: "The user listed in the message logged off the system. Therefore, the user's primary access token, which contains the user's security information and allows access to objects, is erased from memory. After this token is erased, the user cannot access resources such as files or registry keys. When the logoff process is completed, a Security 538 message appears in Event Viewer. If a Security 538 message does not appear shortly after the Security 551 message, a program or service might not be managing its access tokens correctly. Although the user cannot access objects, the program or service might have cached an access token and therefore retained the ability to access objects". See MSW2KDB and ME828857 for details on this event.
