644 Event ID’s not logged

I have a Windows 2000 AD domain. I have auditing turned on for…

Audit Account Logon Events – Success and Failure
Audit Account Management – Success and Failure
This is on the Domain Controllers OU.

The security logs on my DC’s are logging 681, 676, 675

It is NOT logging any 644 event ID’s for account lockouts. I have checked the security logs on all my DC’s. Anyone know why they might not be logged and how to fix it?
