I am revisiting this issue, as it still exists I have a reverse zone (among other things) with nearly 4000 records, most of which are 3+ years old. This zone is set to scavenge, the server is set to scavenge, and the records are not set to 'do not scavenge'. Yet the records persist, months after initially turning the scavenging on. ????? Is there a log for this function? Or some way I can trouble shoot it? Thanks Blake
