Server 2012 DNS Server

Hello,
     I have a small network set up using Windows Server 2012. I have a Comcast Business Internet connection. The ISP comes into a wireless Linksys router which is currently handling the DHCP. I have one physical server and 2 Hyper-V server 2012 set up. One of the vm machines is my DC. I have assigned static ips to all machines. I had some trouble getting the other two machines to join the domain until I pointed them to the DC for DNS. This cleared up that issue but then none of the machines could get to the internet until I put a secondary DNS entry to a public DNS server. What am I missing here? Shouldn't the DNS run through the DC and resolve names to the internet?

Thank you

That is correct that the DC should be used for DNS. Did you configure any DNS forwarders on the DC?

DNS forwarders? No, I am not familiar.
The purpose of them is for when your DC cannot locate a resource internally, to forward the request to outside DNS servers and see if results come along.

Here's a link with how to do it: https://technet.microsoft.com/en-us/library/cc754941.aspx
You only need to follow the section called "To configure a DNS server to use forwarders using the Windows interface"

You could use Comcast's DNS servers, but I tend to prefer Google's (8.8.8.8 and 8.8.4.4)
Isn't this essentially what I am doing by using the 8.8.4.4 as a secondary? Or, if I do that way I would be required to add the secondary on each machine as I add them to the domain?
