I'm setting up a network for about 50 users. I configured a domain controller and DNS on the same server. I have successfully joined my computer on the new domain but I am having trouble accessing most domains on the internet. Our company domain website is hosted externally and I have an A record in the forward look up zone on our DNS server, so it find it and it works just fine. I can also get to speedtest.org, but nothing else.
Locally, I have set my IP and DNS setting manually to internal DNS server and firewall. On the DNS server, I set the IP address to 127.0.0.1 and checked the DNS forwarders and everything appears to be set correctly according to the many articles and forums I have checked.
I also tested by manually setting my local DNS server to external DNS servers, like Comcast, but I get the same results. I'm starting to think that the firewall is blocking this traffic. Is there a way to test this?
