old dns records not getting cleaned up

Hello,

We seem to have a problem with old DNS records not getting cleaned up.  So if a computer is issued a .25 address through dhcp, and then goes away, and that address is re-issued after the lease period, I end up with 2 entries for .25 in my DNS.

Or after 2 years in operation, 5 or 10 records for the same ip.

Can someone assist in helping me get the system to do its own cleanup?

Under DNS, Right click on the DNS server that you would like to clean up

Click Set Aging / Scavenging for all zones and make sure the check box.

No-Refresh interval will define when the timestamp of a record may be refreshed again. The refresh record defines when the recond can be scavenged.

Depending on your DHCP lease time, you can set this to your own prefence. I use 1 day and 2 days for my intervals.

Here's the best article I've seen on DNS aging and scavenging:

It's long but very informative.
