Can not resolve external websites from my LAN

All DNS experts:

I am experiencing an issue where I am unable to resolve external websites from my LAN.  We have internal DNS using Windows 2008 Servers and this functions correctly, however I think I something is not configured correctly so I am able to correctly resolve external websites.

We would be grateful to any suggestions or assistance.

Open the DNS console on your DC. Right-click the server's name in the left pane and select Properties. In the properties window, check the Forwarders and Root Hints tabs. The Forwarders tab will generally contain one or more public DNS servers, either your ISP's servers or well-known public servers like

If that tab is empty, it's probably not a problem, as long as the Root Hints tab is correctly populated. It should look like this:
