| You would also want to enable auditing of logon events on his workstation
| and any other computers/servers that the user may usually use looking for
| failed logon attempts with that account name on those computers. It could
| possibly be that the user is still logged onto another computer [Terminal
| Services or such] with an old password, that a mapped share with
persistent
| credentials is used with old/bad password, or a Scheduled Task is using
the
| users wrong password. Hopefully it is not a jokester on the network
because
| the lockout could be ocurring on any computer that has file and print
| sharing enabled and that would not show up in the domain controller logs
| like a bad attempt to logon the the domain interactivley would. The link
| below is excellent at tips on how to track such issues down about two
thirds
| the way down under heading of "Troubleshooting Account Lockout. --- Steve
