I have 2 windows server 2008 R2 domain controllers but both domain controllers are pointing to Google DNS. These computers were used in a different office location and there was no problem with the network. We recently moved office to another location. On the first day in the new office there was Internet connection and we could browse the web. As at today there is Internet connection but we cannot browse the web. I can even VPN to the office and it works well. Our telephone systems all work using the same Internet connection. I have tried many things but still we cannot browse the web.
