Hello david08,
Instead of scavenging you can also do it this way:

But it will work with 7 days, ofcourse some old entries will stay this time before cleaned up. 12 hours lease time is short, do your users move the machines a lot or work outsdide the office very often?
Best regards

I have a Server 2003 Domain Controller, running DHCP and DNS and I am
trying to scavenge old PTR records and a few duplicate A records. My
question is if my DHCP lease is for 12 hours, do I still leave the
Scavenge settings to the default of 7 days for No Refresh, 7 days for
Refresh and 7 Days for scavenge (main Server setting - not for zone) I
get concerned due to the short lease duration for ip addresses and the
7 day No Refresh interval. My understanding is for the 'No Refresh'
interval, no updates happen to change the timestamp only until after
No Refresh ends then the records can be updated for the timestamp (
Refresh Interval). After those 7 days, then they become eligible to
delete. I realize it's very important to not have the scavenging time
to one day due to servers refresh the timestamps (records) once per 24
hours.
I do not want to delete a server record that is not suppose too. Is 7
day default setting safe for server entries?
Here is one article I read but it did not mention about lease duration
differences.
