I'm reading a technet article ( http://technet.microsoft.com/en-us/library/cc759204(v=ws.10).aspx
), but still being confused.
Looking at below screenshots, I set automatic scavenging period as 7 days for the server. What exactly does it means? If it means it scavenges stale records every 7 days, from what date and time? and how can I reset the date and time to start?
I tried to disable and enable this setting to see if this changes the date and time shown on 'This zone can be scavenged after' on Zone property, but it doesn't change this value at all. If then, now I'm confused for this too, where this date and time came from?
The left screen is DNS server property and the right screen is Zone property.
