Question : Dynamic updates / Scraping DHCP

I have been finding that the list of DHCP clients has been showing older PC's and that all too frequently the related DNS records become stale by pointing to the old DHCP lease.

I have enabled scraping for the DHCP and Dynamic Updates for the DNS and although the DHCP seems to be accurate the DNS still has a lot of old entries.and although I can clear them manually I would rather Dyanmic Updates do that for me.

I have had a bit of a read of http://support.microsoft.com/kb/816592 regarding Dynamic Updates but haven't seen anything that should stop me doing this.
