SYMPTOMS
Security audit event 642 is logged when a property of an Active Directory user or machine account changes (if Account Management auditing is in use on the domain controllers). If the change involves turning on, turning off, locking, or unlocking an account, the event description identifies the relevant operation. Other changes to the account that affect the userAccountControl attribute (for example, the Password required setting) are logged as a generic "Account Changed" audit event.
CAUSE
This problem occurs because SAM explicitly audits only changes to the "account disabled" and "account lockout" flags.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
MORE INFORMATION
After you install this hotfix, all changes to the userAccountControl attribute flags are identified in the description field of audit event 642. This includes the following items from the Account tab for a user account (in the Active Directory Users and Computers snap-in):
- Password never expires
- Store password using reversible encryption
- Smart card is required for interactive logon
- Account is trusted for delegation
- Account is sensitive and cannot be delegated
- Use DES encryption types for this account
- Do not require kerberos preauthentication
For additional information about the flags in the userAccountControl attribute, visit the following Microsoft Web site:
Note that two flags appear with these options in the Active Directory Users and Computers snap-in but are not changes to userAccountControl. Therefore, these flags are still audited as generic "Account Changed" items: "User cannot change password" and "User must change password at next logon."
The first is a change to the security descriptor on the account object. The second is a change to the pwdLastSet attribute. You can identify both of these by turning on Directory Services auditing. This provides details about which attributes are changed during a modify operation.
