housekeeping in DNS


We are running DNS in a windows 2003 environment, and I recently noticed that I am seeing more than 1 host A record for an ip address. How can I do an automatic clean up on my DNS?

Any help appreciated.

You should look into setting up Scanvenging Stale records on the DNS server

Sorry - my spelling is rubbish today - scavenging stale records

good. Should I use the default of 7 days?

You could, but I normally set mine to 1 day because a lot of laptops keep coming and going on the network...

I choose this option

"In the console tree, right-click the applicable Domain Name System (DNS) server, and then click Set Aging/Scavenging for All Zones."

I set the no refresh interval as 7 days, refresh interval 7 days, and applied these settings to the existing AD-integrated zones

I did this for both of my DNS servers.

I am on the right track?
Chris MillardCommented:
Yes. It won't necessarily have an immediate effect, but what you've done sounds OK.

If I leave the config  that I did above, and I use this option below and set it to 1 day. Would it cause any problems?

To configure automatic scavenging of stale resource records
Open the DNS snap-in.

In the console tree, right-click the applicable Domain Name System (DNS) server, and then click Properties.

Click the Advanced tab.

Select the Enable automatic scavenging of stale records check box.

To adjust the scavenging period, in Scavenging period, select an interval in the drop-down list (either hours or days), and then type a number in the text box.
