I have a Windows 2000 server and I've noticed that there are quite a few stale records.
Scavenging is set for the zone, as per screenshot, the DCHP server is set to update DNS for clients.
One example is a machine that is showing in DNS with the records timestamp as 31/07/2007. The box is ticked to delete the records when it becomes stale. The owner of this records is SYSTEM. This is not showing in DCHP with a current lease. There are other records that have more recent timestamps, eg 03/06/2008 which are still showing in DNS.
A output of dnscmd /zoneinfo is on the attachment.
My question is why have these records not been deleted from the zone?
The scavenging is set on the reverse lookup zone as well, however has not been enabled at the server level. I am worried about enabling this without knnowing what's happening with these records.
Any advice would be much appreciated.
Thanks in advance
