Re: Locked out local admin accounts...

We are having a similar issue here. An admin account  gets locked out 
constantly. Logs surrounding the lockout for the account are all 
successful.
We have an active directory  with Win2k3 servers and XP for workstations. 
The single account having this problem happens to be placed  in the local 
administrators group by a group policy.  At first I assumed there was some 
script running that had a wrong password in it. Thing is there are no 
failed log-ons for the account around the time of the lockout. So a wrong 
password does not seem to be the case. Anyone know if there is a way an 
account could get locked out other than numerous failed log-ons? 
 Anyone else having a similar problem or have any ideas as to what could 
cause this?

Locked out local admin accounts...






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.

This is very bizarre.

Thanks for your help,

Ryan Murphy
