where does the server get internet DNS?

[itsolar]

Hi, Running win server 2012 r2

 

Just setup ,AD,DHCP and DNS. Able to connect a win7 client via the new domain from the server. That client can see the internet. But the server can not see the net.

 

I was told to turn off all other DHCP devises on the network. And let the 2012 server handle the DHCP.

I set the server nic IP4 to the routers ip, No

I set the server nic IP4 to the TW modem, No

So were does the 2012 server get internt DNS?

 

any help would be great, thanks

Server IP should not be the same as anything but on same subnet as router.

 

So if router on 192.168.1.1 then server can go on 192.168.1.2.

 

DNS should be set to same as server IP and then the Forwarder set in DNS server manager to point to ISP DNS

Firstly as @snagrat said the servers IPv4 address should be set differently to any other device on the network. Secondly you need to setup DNS service with forwarders to lookup external addresses. To do this go to the DNS console and right click on the server in the tree, click properties then select the forwarders tab. Enter in your isp or preferred dns providers.

If no forwarders are specified then it will use root hints to resolve dns.

Hi itsolar

There is no need to use forwards as root hints will work perfectly, the DNS setting on the network card in your server should be set to 127.0.0.1, i.e. pointing to it's self.

If you use forwards to point to your ISP's DNS server it will work but will slow down external DNS lookup as all external requests will be forwarded to your ISP's when your local DNS will be able to reply much quicker.

The only thing I would recommend would be to update root hints, if you click on each root hint in with in the DNS server control panel there is a button you click but I can not remember the exact name on the button maybe update or resolve.

Hi,

 

WOW, Thank you all for your reply's! It turned out I had the wrong subnet in the ipv4 for the nic card. I pointed it to the router and BAM online. Again thank you all for you help.
