Is it feasible to disconnect your router/connection to the outside world? That would be informative to see if the attack/issue is internal or external. _____ From: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, January 04, 2005 9:39 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] OT: HELP! All domain accounts getting locked out! All 1000+ of my domain accounts are being locked out. It's like someone is trying to brute force the accounts directly, but I can't say if that's the case or not. This has been going on for about an hour. I'm not sure how I can track down from what machines these accounts are all being locked from. On my DC's I'm just seeing failed logins because of locked accounts, but not the lockout attempts logging.
