my DNS scavenging is not working as I expected.
I have setup DNS scavenging like this on all of my domain controllers:
No-refresh interval: 4 days
Refresh interval: 4 days
and under properties --> Advanced I have Scavenging period: 7 days
My DHCP server is on one of my domain controllers and the lease duration is set to 8 days.
I turned the scavenging on about 3 weeks ago, so it has been running a couple of times already, but in the event viewer it gives me Event ID: 2502 and says:
The DNS server has completed a scavenging cycle but no nodes were visited. Possible causes of this condition include: 1) No zones are configured for scavenging by this server. 2) A scavenging cycle was performed within the last 30 minutes. 3) An error occurred during scavenging.
When I go to Zone Aging/Scavenging properties of the zone that I want to scavenge I can see that it has incremented my "The zone can be scavenged after:" by 4 days. I guess that's my "No-refresh interval" doing that? I hope someone out there can tell me why it's not working! :)
