What is the best practice for configuring redundant DC/DNS servers. They are both GC servers, and both in the same site. Should the primary dns point at itself, or the other server? DHCP assigns them to the workstations as DNS1 primary and DNS2 secondary. Using the following nomenclature DNS1 and DNS2... DNS1 ip settings: primary=DNS1 secondary=DNS2 DNS2 ip settings: primary=DNS2 secondary=DNS1 OR DNS1 ip settings: primary=DNS2 secondary=DNS1 DNS2 ip settings: primary=DNS1 secondary=DNS2

Hello, The IP address settings in two DNS servers will be like DNS1 ip settings: primary=DNS1 IP-Addr secondary=DNS2 IP-Addr DNS2 ip settings: primary=DNS1 IP-Addr secondary=DNS2 IP-Addr Regards, Ravikumar P

The recommendation is to use another DNS server as the primary DNS server on the network adapter. You may use the local DNS server (I set the loopback address) as the secondary or tertiary DNS server. However it should not be first on the list. Edit: So in your case, the second example is the correct server order.

Hi, Thank you for the post. Neil Frick is correct. You could run DNS server Best Practice Analyzer via Server Manager to know it. DNS1 ip settings: primary=DNS2 secondary=127.0.0.1 DNS2 ip settings: primary=DNS1 secondary=127.0.0.1 http://technet.microsoft.com/en-us/library/dd378900%28WS.10%29.aspx http://social.technet.microsoft.com/Forums/en/winserverNIS/thread/b29bb944-3a06-4ac4-a831-1fd22f64f71e If there are more inquiries on this issue, please feel free to let us know.
