Domain account keeps locking!

Hi we have a few users who accounts keep locking even though they have not put their passwords 5 times, it often happens when they are already logged in.
 This then stops their internet access through our proxy as the Domain account cannot authenticate because it is locked

I have done some research and one suggestion is to delete the account and recreate it?! Will this cause issues for file access done through windows security?

In order to find out exactly why the accounts are locking out you need to enable Active Directory Auditing on the Default Domain Controllers Policy.

You would then need to reference the security logs on the domain controllers. If you have many DC's in your environment then you will need to check all of them becasue the account could be locking out anywhere.

Lepide software has a great tool called Active Directory Auditor which will provides hundreds of reports and it will tell you exactly where the account is being locked out from.

I have seen this done when the credentials manager on the system has an old saved password or a mobile device has an incorrect password on it.

On the machine click the windows button and type credential (credential manager should pop up).  Check that they don't have any saved passwords stored

check that all saved passwords are updated or removed from Windows Credential Manager.
Open Control Panel, User Accounts, on the left "Manage Your Credentials"

Hi Guys
 The credential manager doesn't seem to be the problem as we have cleared all passwords and restarted, it has happened 3 times this morn :(

Maybe i'll try the audit software to see what that comes back with?

thanks
