Hi,

I have many domain controller and RODC in WINDOWS 2008 SP2.

I have many administrator account loocked and i am not able to find the root cause.

When i connect to the server, i and after i enter my password, i have this message:

"the referenced account is currently locked out and may not be logged on to"

Other administrator have the same issue.

After 10-20 minutes, the account is unlocked automaticly.

A/c lockout can be with many reason & there can be conficker worms too which mainly target admin accounts.

There can be password guess on the account & you can use netwrix tool to detect.

There can be many reason as i said,mapped drive or service account & its password has been changed, virus attack, if all the domain & admin account facing the issue it can be surely conficker.

Try to cut down the issue,use netwrix tool which helps actually.

Sometime i have seen SEPM is not able to detect Conficker,try to use Mcafee,SOPHOS or trend micro.
