I am guessing this is an old Blog:
there are several questions to be asked: are you running VM on Hyper-V what are your Hyper-v switch settings ? are you on the same subnet as your Edge router ? also check your DNS settings ? Subnet mask. is DHCP enabled ? there are bunch of things that could block your internet connectivity. here what I would do either configure a proxy on an authorized server not client, enable DNSSEC and Flooding guard on your AD Server, import the proxy settings from IE using NETSH.
so if your AD Server does not have a global DNS zone it will not handle any Internet requests including your own AD server requests. once you add a global zone to the AD Server itself it will expose your server to the global network.
