Scavenge old dns ptr records - windows 2000/2003 AD integrated DNS
Posted on 2007-04-04
I have a windows 2000 and 2003 dc's running AD integrated DNS. I have noticed my reverse lookup zone that corresponds to my main user DHCP subnet I have many, many duplicate records resolving to various old machine names. I saw that scavenging of stale records was not enable on this reverse lookup zone...but it was enabled on the corresponding forward lookup zone. I have since enabled scavenging on the reverse lookup zone. Refresh intervals are set to the default of 7 days.
Have I taken the right step to ensure my PTR records are current and only reflect the current information?
