I have a DC on a network that is working perfectly for the LAN and was working on WAN until recently. I've check dns, it will not ping 18.104.22.168 it will ping the gateway. I have users using it with no problem on VPN and locally. the strangest thing is it will resolve with an IP address if I ping www.google.com
it resolves to 22.214.171.124.
I've flushed DNS, rebooted server, I'm not sure what else to do. Any ideas?
