Using the auditing mechanism
In Windows Server 2008 R2, as in Windows Server 2008, you can use the Active Directory Domain Services (AD DS) auditing mechanism with the Directory Service Changes audit policy to log old and new values when changes are made to Active Directory objects and their attributes. We recommend that you implement auditing in your Active Directory environment to track all object deletions, object deletion times, and the account names that perform these object deletions. For more information, see the AD DS Auditing Step-by-Step Guide (http://go.microsoft.com/fwlink/?LinkID=125458).
