Are you sure that you are auditing failed login attempts? Any other strange
behavior other than the accounts being locked out? What does perfmon tell
you? Are the systems under heavier load than usual?
Also, how large are the timestamp gaps in your event logs? Is there anything
to indicate that event logs are being deleted? Do you have any applications
that you use which login into each system remotely using that account? Also,
were you using the same password for each machine?
