LAN AND CONDITIONAL FORWARDING

I have a question in regards to LAN and subsequent access to the internet. If you wanted to protect your LAN from the internet would this scenario work as a sound measure. On the LAN delete root hints in DNS, provide a conditional forwarder to the router or ISP. I am a student and I am attempting to make sense of the security and the realm of possibilities that may exist in protecting the LAN from the internet. THANKS in advance for the comments.

Thanks. We'll let you know when a new response is added.

Microsoft’s Active Directory, Group Policies and ISA server will accomplish all of these tasks and more. There are other options of course but they may be more complex and not as well integrated as these tools.

Removing the root hints from your LANs DNS server will do nothing but cause your clients on the LAN to stop resolving public DNS.
