Hi,
I know there are number of people who have asked this but I have a few specific questions in regards to this. A few months ago I had to set up scavenging on our DNS server which wasn't scavenge stale DNS records. I ran in to a great article which mentions step-by-step on what to do and where things can be set up. Unfortunately, I can't find that article anymore but I remember DHCP - Enable Name Protection was mentioned in the article. As it turned out, this option got my scavenging to work.
So questions:
- Is this option in DHCP necessary to be turned on for scavenging to work properly?
- We have a lot of DNS entries that are valid but are over 3 months old and they are not showing up as static. These reference to servers ofcourse and they should be static. How do I make the timestamp of these servers to be more recent so when scavenging works, those entries wouldn't be deleted.
When I did this at my previous work we only had about 800 DNS entries but at my current work they have over 4000 entries. A lot of which are showing up as old entries (more than 3 months) but they are active and valid.
I also remember that I lost about 5 DNS entries at my previous work when scavenging kicked in but they were easily created after.
I don't want to run in to situation where valid DNS entries get deleted because the timestamp are old. Would a restore of DNZ zone work if valid entries get deleted?
Please help.
Thank you.
