Solved DC without DHCP could still browse internet if DNS down?

Specs: Windows 2012
I have a Server2012 DC box and it is acting up at the moment. We're in the process of replacing it. In the mean time, I would like to find a way so that if the box goes down, users inside could browse the Internet. Here is my theory, correct me if it would not work. I will turn OFF DHCP on the DC, turn ON DHCP on the Firewall (which DC is plugged into). If the box goes down which means the DNS also goes down but could the LAN users still be able to access internet?

✔ Best Answer
You can't browse the Internet without DNS. You will need to set the DHCP on the router to give the server as the primary DNS server for clients and the router as a secondary DNS server. That way, if your server fails users will still get DNS services.

But, in your position, I would set up another server as an additional DC. It doesn'tbhave to be server hardware; just a normal PC running Windows server would suffice. Apart from anything else this is going to make life much easier if your main server fails.
