I have a service account that runs scheduled tasks and services. It is being locked out every Saturday at 11 PM, but I don't know what is locking it out. I'm needing to know what machine/IP the invalid attempts are coming from. I know Microsoft has the Account Lockout & Management tools, but I'm running Active Directory on Server 2008. Will these tools still work? If so how do I put them in place? Is there a better option out there?
