When you configure a DNS server on a DC, do you reference it in the preferred DNS server in TCP/IP properties?

Server A (Primary DNS Server)
IP Address 192.168.0.3

Server B (Secondary DNS Server)
IP Address 192.168.0.8

On Server A, do I add under preferred server in TCP/IP,
192.168.0.3 or 192.168.0.8?

On server A under preferred server in TCP/IP you add 192.168.0.3 as the primary
and on server B under preferred server in TCP/IP you add 192.168.0.8 as primary and 192.168.0.3 as secondary DNS

To further clarify clonyxlro's correct Answer, DNS servers, especially AD integrated ones, should always point to themselves as the primary DNS server.  You can have secondary, tertiary, etc., DNS servers, too, but they always need to be internal, AD aware addresses.  What you DON'T want to do is point to an ISP or any external DNS server in the NIC properties.

So it should look like this?

Server A (Primary DNS Server)
IP Address 192.168.0.3
Preferred DNS Server 192.168.0.3

Server B (Secondary DNS Server)
IP Address 192.168.0.8
Preferred DNS Server 192.168.0.8, 192.168.0.3 or
Preferred DNS Server 192.168.0.3, 192.168.0.8

Server A (Primary DNS Server)
IP Address 192.168.0.3
Preferred DNS Server 192.168.0.3
Secondary DNS Server 192.168.0.8

Server B (Secondary DNS Server)
IP Address 192.168.0.8
Preferred DNS Server 192.168.0.8
Secondary DNS Server 192.168.0.3

Notice each server looks to itself as primary?
