I'm not sure what your comment means. My understanding is that a DNS
client wont query the secondary if it doesn't get the info it need from an
online primary.

DNS Clients have no concept of "Primary" or "Secondary" for
resolution -- they use one DNS server as "Preferred" and others
as Alternate(s).


It will only query the secondary if the primary doesn't respond.

That is true -- I have been saying that all along explicitly.

It is INCORRECT to configure a DNS Client with multiple DNS
servers which don't return the SAME information, that is, which
cannot resolve EVERY request the DNS Client will ever legimately
make.

It should work so long as the primary DNS server is completely offline.
Is DNS is running but not responding with the right info it wont fail
over to the secondary.

All DNS Server used by the clients must return all of the correct answers
the
clients will ever legitimately need.

Hi,
I have 2 Windows 2003 Servers with ONE running DNS, i am thinking of
putting
a second DNS internally to handle requests if the first goes offline
or gets
rebooted, can i just install a second DNS server on one of the other
servers
and configure them both to replicate info between them, then give all
my
clients both dns server address's.

When the first server is offline you need to change your AD clients to
use the second DNS server as the "preferred" DNS server.

Are there any performance issues in doing this, is there anything i
need to
be aware of before i start this if i can indeed do it ?
