I'm looking after a fairly large enterprise system with a few thousand
Desktops and several dozen servers.

There's a number of W2003 Domain Controllers distributed around various
sites, providing DNS support.

Most of the Desktops/Laptops use DHCP, the servers are generally static.
Some DNS entries have been added manually.
The systems have been around for a few years and the DNS (forward and
reverse zones) are now full of entries which must be obsolete, and confuse
things greatly, particularly reverse lookups.

We (seem to) have aging and scavenging turned on, but the number of entries
don't seem to be reducing.

I understand that AD keeps some sort of age information for dynamically
added DNS records (which underpins the scavenging). I think, if I can see
this, it may help me understand why scavenging isn't working, and also
identify those entries added manually.

Is there a way (via scripting, or even via a utility or GUI) to list out the
DNS entries with the age (and related) information?


Thanks
Bob
