Hi
The tool that Paul points to is useful. I find it more useful in context
with some other tools:
Also review:
http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/bpactlck.mspx
What I generally do to troubleshoot these problems is:
1. Use lockoutstatus to determine which DC's the bad password attempts are
registering again.
2. Enable auditing (as per the document above) and look for lockout events.
3. From the lockout events, determine which clients they originate from.
4. Look at the frequency of events to determine if it's a user issue or
process driven.
5. If user related, educate user.
6. If process related, implement Alockout.dll to find the offending process.
Kind regards
