Setting Up Multiple DNS Server on a Network
Wayne & Carr
We have " 4 NT4 Server " & " 1 Win2k3 Server "
In our network.
One of the Server's (Which Host Web .... NT4 ) Runs DNS ( Default DNS
Server )
We are wanting to setup the other 3-NT4 Servers, to host DNS as well.
But are not quite sure on how to go about it?
Setting them up like the existing one, will be no problem to do.
But are not sure what measures to take, and configurations that
May need to be made, in order to make it an easy going process.
I have heard that you can have a "Backup DNS Server"
This is similar to what we would like, but we also have
3 more NS Records, that we would like to use on the other
DNS Servers as well. So this is where we are having the
Issue's on, is: ?
How to setup the other DNS Servers ( As Backup or Self Runed DNS ) ?
Thank You All

IF you wish to host the same zone, e.g., YourDomain.Com, then
just install DNS Server, create a zone for the same (existing)
zone, and make it a SECONDARY.
Secondary servers must be configured to use an existing
DNS server to pull their changes. Normally this is the
Primary Server for the zone, but may actually be any of the
servers for that zone.

Install DNS
Create zone
Make it a secondary
Point it to the Primary or other DNS server for the zone
Make sure the NS (+ A) records for the Secondaries get added
(at the Primary) if you wish

Secondary

Got a few question for you? ( First what I have done already )
To begin with,,, I have added
New Server #1 = ( Primary DNS Server to the list, and all Domains are listed
on the 2nd server )
New Server #2 = ( Then I created new zone: And added in the information (
Through the use of the [Hand Cursor] )
Reading the information at the beginning of "Creating the Secondary Zone"
it states:
Secondary Zone's are "Read Only Zones".
Would this be the best way to do this? I mean, to begin with, I have several
NS Records,
That need to append to DNS.
Would I add the new " NS Records " to the Primary DNS Server First?
And when the Zone Transfer takes effect, it will be listed?
----------------------------
Or Would it be best to recreate all Zones as Primaries?
On the other DNS Servers? And if so. What steps would
I need to take to insure that there is no conflicts in Lookup's and Zone
Transfers?
For the Serial Numbers? ( Also can you do Zone Transfers on Primary Domain
<-> to Primary Domain ? )
( Read this on the Internet, do not know how accurate it is )
Can I copy the DNS Files from the Master DNS Folder over to the
Other DNS Servers and add them in this way, instead of recreating the Zone
All over again, as " Primary Zones " Instead of Secondary Zones ?
Thank you for any other information that you may be able to assist me with.

Install DNS, add a New Zone, choose Secondary and point to the first
DNS as primary. Configure the primary to allow zone transfers to
those secondaries.

Added WHAT information?
Server #2 needs to be a "Secondary" with #1 as it's master
and then PULL the data automatically.

Correct -- you only EDIT the Primary and the Secondaries pull
from the Primary (or from another Secondary.)

First or last, doesn't matter really -- as long as you do it.
> And when the Zone Transfer takes effect, it will be listed?
The Secondary will copy the whole thing when it boots and
every "refresh interval" (or at least the incremental changes.)

Every zone needs ONE primary, as many Secondaries as
you wish.
[Note: There are special cases for "shadow zones" where
internal (AD) and external (Internet) use the "same name"
and also when you use "AD Integrated DNS" but this won't
affect you for now.]

Primary for A ZONE is where you edit changes -- Secondaries
do "zone transfers" to copy the zone.

No. And MS DNS MMC manages the "serial numbers" so
LEAVE them alone.
If you do mess up the serial numbers, make sure Primary is
HIGHER than all secondaries or they won't transfer from it.

Possible but you would probably mess it up and you can do it the
way I described above much easier.

ONE Primary PER zone.
