Hi all
I've enabled, on my domain (win srv 2008), the Account Lockout Policy.
I have a problem with only 1 user (in total they are 80, more or less).
He finds randomly his account locked, but he does not use a wrong password (at least, not 10 times as GP!). It happens 2-3 times every month.

In event viewer I cannot find anything regarding these locks

He uses:
- pc with Windows 7
- mac with parallels for a Windows 7 machine
- iPad
- iPhone

Any ideas?
Thx

Go here

Download the lockout tools, it will scan your domain controllers and you should be able to find where the account is locking out. Go to said computer and you'll probably find something like a scheduled task or the account logged on with an old password.

nice tool, but from there I can see on which DC is locked (when he is): or I am using it in the wrong way?

I read that I should look for an event id 4740, but I cannot find it anywhere.

If you open eventcombMT and then at the top click searches, built in searches, account lock outs :D

:-(

Not sure then, it could be that he's actually just locking out his account by accident and doesn't want to admit it... :S

The other thing I would check is your current Security log size, if it's not large enough it'll only keep data for the day rather than historical data, you may need to change that so you have the logs to scan in the first place.

Regards

What is your account lockout threshold? Microsoft suggests keeping it at 10.
