DNS Scavenging issues

By eporteni ·
We at one time had turned on DNS scavenging so that it would clean up the old DNS records after 7 days, like normal, right? This was when everytihng was initially being built out. Well, one thing led to another, and when it was turned on, all the DNS records were scavenged.
it's been about two years since scavenging has run, and we are again looking at turning it on. The issue now is that we would like to find a way to give a report of all the "old" records in DNS - old being for machines and aliases that do not exist anymore on the network or in AD - so that we can make sure those get cleaned out after scavenging is turned on. Does this make sence? I have tried usign DNSlint, DNScmd, and even trying nslookup, but I can't figure out how to pull a report listing the age of the records, which records will maybe be scavenged, or even scavenge the records for items that do not exist anymore, leaving the "good" ones in place.

Thanks in advance for the help.

Old records

by p.j.hutchison In reply to DNS Scavenging issues

First, we made sure that certain records should not be scavanged, such as servers, by ticking box 'Do not scavange' or equivalent.

Then we enabled scavanging for old records more than 28 days old on only ONE DNS server to ensure scavaging only takes place once on one server, then left it alone.
