DNS reverse lookup not updating automatically

I am running windows server 2003 and DNS and I noticied that I have a lot of OLD stale records in my reverse lookup zone in my DNS server.

How do I fix this?   I can delete all of them, but that doesn't fix it, as I deleted some manually a while ago.  Is there a setting in DNS somewhere to automatically update the reverse DNS pointers when a PC changes it's IP address?

got it, so you're saying just check the box "scavenge stale resource records"
Also, on the
no-refresh interval

They both say 7 days
Should I need to change anything?

Maybe I should make it 1 day, as my DHCP lease is set to 1 day?

Yes, you could.  I wouldn't do the scavenging on your primary domain (Ie domain.local) as if you have static entries (which everyone does for printers, routers, switches, etc) these will get scrubbed.  The reverse lookup zone is pretty safe to scrub.
