Check out http://blogs.technet.com/b/networking/archive/2008/03/19/don-t-be-afraid-of-dns-scavenging-just-be-patient.aspx

I'm not sure if that exact process is the same in more recent versions of Windows Server.  If it is different just Google for "windows dns aging scavenging" plus your version -- there are tons of links out there.

As a reminder, setting directory access auditing will create a storm of events in your security log.  In most production environments, you can expect thousands of "noise" events for every malicious DNS deletion, so this probably needs to be used sparingly.
