Primary and Secondary DNS configuration

[Do]

I want some fault tolerance with my DNS design in Windows 2000 Server.
I have one DNS server and in the NIC TCP/IP properties,
I correctly have the primary DNS server set to 127.0.0.1.
and the second one set to my other DNS server.

The other DNS server has it's primary also to 127.0.0.1.
And the secondary set to the one pointed above.

Is this design correct? Is it safe to assume that if one servers power
turns off,
the other server will handle the DNS?

It is not correct to use 127.0.0.1 loopback address, that will cause
registration problems. You should use the IP of the private interface. Then
you need to go into the DNS server properties on the interfaces tab and set
DNS to listen only on this IP address. DNS will create a host for each
address DNS listens on so it needs to listen on the IP you use in TCP/IP
properties, except 127.0.0.1 that IP is always localhost which will not
register in your AD zone as a DNS server address.
