Win2003

This event does not get logged by Windows Server 2003 despite MS documentation. It is replaced by 680 type Failure Audit.

In Windows Server 2003 Microsoft eliminated event ID 681 and instead uses event ID 680 for both successful and failed NTLM authentication attempts. So on Windows Server 2003 don't look for event ID 681 and be sure to take into account the success/failure status of occurrences of event ID 680.
