When auditing logon and logoff failures on a Domain Controller, not all expected failure audit event messages are recorded in the Security Event Log of a domain controller.
This behavior may occur if a user does not log on to a member Windows NT workstation or server by using an account that has domain credentials. In this case, the local Security Log records an Event 529 (Logon Failure) event message. There is no failure audit recorded on a domain controller when the domain user's logon does not succeed. The account may be locked out if configured to do so, but no event message is recorded.
You cannot force the domain controllers to log this failure audit. However there is an event message to audit the locking of an account on a domain controller. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
