I have a Hyper V lab with 5 servers currently running Windows Server 2008 R2 by Microsoft. I have ran dcpromo.exe and ran through the wizard for creating a domain controller and setting up DNS.
I have added all my servers to the domain and pointed their DNS addresses to my main AD/DNS server. However, these servers cannot get access to the internet. When I change the DNS to google's dns such as 8.8.8.8 they seem to browse the internet correctly. When Windows server installed DNS it used the wizard and I selected "what I thought" were all the basic options.
I am using a Linksys router behind all of these Hyper V servers. My HyperV host gets access to the internet and its DNS is pointing to my router. (192.168.6.1)
What are some common DNS troubleshooting tips to get this resolved? Like I said, I havent done anything with the DNS except let it install as the standard DNS. I ran the best practivce analyzer and it came up with some Clock time errors but I think thats because im running the ADC virtually and they don't recommend that.
Thanks in Advance.
did you put the isps dns servers ips in the forwarders in dns? Answers are only as good as the information you provide.

No, I did not. Would that be a part of the "Creating a Forward look up zone"?
not completely expand dns under your domain name for the forward lookup zone. you will see forwarders. input the isp dns servers ips here.
way this works is the wksts point to the server for dns. then send a request for a local name and the local dns server resolves it. when they make a request for yahoo.com the local dns doesn't know who that is so it forwards it to who is listed in forwarders. answer is returned and passed to the wkst.

I was able to get DNS to resolve. Thank you very much. What I did was went to my root DNS in the DNS MMC and added my ISP's DNS address in the forwarders tab. Is this a common practice? So im assuming without this my DNS server cannot resolve w/out going through my ISP.
That is correct. It is a commonly missed step Your dns server is not a internet but local dns server. It needs the internet dns server to resolve internet names for it
