To minimize the occurrence of unexpected results when users browse the Internet in the future, Chad should enable the Secure cache against pollution setting in the advanced properties of the server.
Key Takeaway: When the Secure cache against pollution setting is disabled, all records received in response to DNS queries are cached. This happens even when the records do not match to a queried domain name. Enabling the Secure cache against pollution setting disables the ability to pollute the DNS cache with incorrect information and to spoof DNS queries. With Windows Server 2003, the caches are secured against pollution by default. This will prevent users browsing the Internet from being directed to the wrong websites.
