I have a problem in my Windows 2008 Active Directory.
I haven't found this case in Event Viewer and also still can't search Event ID. The problem is that one Active Directory user is locked frequently in the morning when he opens his computer. He is using Ubuntu 12 Desktop. The problem is that he can't login to IM or the Windows network to access the fileserver.
I usually unlock his account in AD each time but that is not a solution because I haven't found any related error log ID in the event log.
