Hello:

Question: Currently, we have two DNS Windows 2000 based DNS servers,
one is a Primary and another one is a Seondary. If I am adding another
server for disaster recovery, wondering whether I have any other
methods other than configuring the new server as a seondary zone
server in which case, I will have to temporarily disconnect the
existing secondary DNS server from the network.

In other words, can I have more than one secondary DNS server with
indentical DNS configuration?

Quick response will be appreciated. Thanks!

Victor

Hello Vrao,

Yes you can have more than one secondary DNS servers.

Of course, that is the traditional DNS configuration, a SINGLE
Primary and a set of Secondaries (as many as necessary for fault
tolerance and performance issues.)

Each secondary can pull from any of the pre-existing servers for
that zone -- many people don't realize that a Seconary can choose
another Secondary for it's master, allow you to control distributed
DNS servers more flexibly.

[Example: One Secondary in Africa pulls from a European DNS
server, and the other Secondaries in Africe pull from the first
Secondary as their "master".]

With AD Integration you can have a set of DNS-DCs that act
collectively as a "set of Primaries" -- this works because the
AD-integrated set takes advantage of Active Directory's "multi-
mastering" capabilities.

Great...thanks.

Hi Martin:

Thanks for the response. One clarification. When you say, "Pull," I am
assuming you are referring to zone transfer initiated from the
Secondary DNS Servers?

Victor
