DNS againg/scavenging doesn't seem to work?

[ADB100]

I have DHCP configured with the majority of scope leases set to 3-days. On the DNS server I have enabled automatic scavenging of stale records globally and set it to 2-days. I have verified that 'scavenge stale resource records' is checked on each of the DNS zones (including the reverse lookup zones) and the refresh & no-refresh interval is set to 2-days.
When I look in the main forward lookup zone for the domain I have dynamic records for hosts that were shut down a while ago which should have been removed automatically (the checkbox 'delete this record when it becomes stale' is checked). I have also manually ran a scavenge and the records remain.
What am I doing wrong?

Thanks

Andy

Surely somebody enables scavenging/aging of DNS records?

are you set to always update dns? if not, do that. is dhcp running on the DC? were they statically created or dynamically updated?

If its a AD zone if you didn't setup dhcp with the correct account to register the records you could have some problems with scavenging due to security

I kept on looking and found some references to servers being shutdown and the scavenging service not being happy if it hadn't been active long enough. I shut the server down (it's at home in a 'test' environment) quite a lot so I think it's to do with this.
Any other people who are in a similar environment please reply as I am keen to see if it's just my frequent shuting down that's preventing the scavenging working correctly.
