| Description | User initiated logoff: User Name: <User Name> Domain: <Domain> Logon ID: <Logon ID> |
| Event Information | According to Microsoft : Cause: As , 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. 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. Resolution: * If this message is followed by a Security 538 message, no user action is required. * If not, verify that all services and programs are updated and identify which of them might be causing this failure.
