Re: obsolete DNS entries in AD-integrated DNS



There are actually two places you need to enable scavenging. The one as
listed by Keshav and on the server that is to do the scavenging. It is
recommended to only have 1 dns server scavenge for each dns zone to be
scavenged.

See my other post that will link you to a how to for scavenging.

You could probably use the Scavanging/Aging options of the DNS server to
delete DNS records that have not been updated in a defined period of time.
Open DNS Management console > Right-Click the DNS server > Properties. You
have the options there under "Advanced"

How to set the DNS server to drop those obsolete entries?
Thanks,
