In our environment today, local administrator accounts on workstations and servers have been getting locked out at an alarming rate. Nothing crazy is standing out on the IDS, and the security logs on the machines that are having the administrator account locked out aren't showing any login attempts. What could be going on here? We're a Win2000 environment, and domain accounts seem to be unaffected, it's only the local administrator accounts that are getting locked.
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? -- Miles Stevenson miles () mstevenson org PGP FP: 035F 7D40 44A9 28FA 7453 BDF4 329F 889D 767D 2F63 --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute.
