Just an FYI...

Every version of Windows since Windows 2000 (sans Windows Me) has had the DNS Client service which maintained this 
caching function. This was by design due to the massive dependency on DNS resolution which Active Directory has had 
since its creation. It greatly reduced the amount of repetitive lookups required thereby speeding up AD based functions 
and lessening the load on DNS servers. It still exists today up through Windows 8. You can disable the service, but it 
will also break DDNS updates unless your DHCP server registers hostnames on behalf of your clients.
