Prior to NT 4 SP4 message about the user account being locked out were only
written to the security log of the workstations or servers where the events
occurred and were not written into the security log of the domain controller
where the error occurred. At that, the error message was only written if the
audit policies were enable on the workstation. SP4 does what one would expect
and writes these messages on the domain controller where the bad password limit
was reached but ONLY if the audit policy for the domain enables Success
for the User and Group Management audit category.
