Does DNS have to reside on a Domain controller |
|
|
We are about to take the plunge and unpgrde our nt4 PDC.
Hre is my current setup
Server 1 - NT4 - PDC - Wins
Server 2 - w2k3 - mbr - F/p
Server 3 - W2k - mbr - Sql
Server 4 - NT4 - mbr - exch 5.5
Server 5 - w2k3 - mbr - Print server
Server 6 - w2k3 - mbr - ---> DNS <---- - Web monitoring
Server 7 - NT4 - BDC - utility
Server 8 - W2k3 - Standalone - VPN
I created a standalone test BDC (TESTLAB), then took it to another seperate
enet network, promoted it to PDC, then did an in place upgrade; with NO
problem. NOTE that when I did this AD install automatically put the DNS on
this "TESTLAB"
Wy question(s) is/are....
1 - Will the inplace upgrade in question work on my production PDC
(server1), even if the DNS will not be located on that machine PDC(server1),
or does AD REQUIRE that the DC(server 1), host the DNS?
2 - Is there a point in the upgrade AD installation where I can / will be
able to tell the DC (Server 1) that my DNS is located on Server 6?
3 - would it be better to just scrap the DNS on server 6 and setup DNS on
Server 1?
Thank you...
Divin in and takin the plunge..!!!!! |

No, but that is a generally good place in Microsoft
networks.

Yes, it knows you need one, so if you have no DNS and agree,
DCPromo puts DNS on that DC during the upgrade.

Yes, but if you have a pre-existing DNS you need to make sure it
is DYNAMIC for the required Zone BEFORE the upgrade.

Yes.

Better is a relative term, both work and are technically
pretty much equal.
I would not in any case "scrap" the existing DNS in most
case but might replace it.
If the DNS zone is seriously populated you will want to
keep the existing records so you either use the existing
DNS or if you wish it to be on the DC you move it ahead
of time OR afterwards.
Moving it is trivial this way: Make the new (to be) DNS
server by installing/enabling DNS and creating a SECONDARY
for the existing zone, thus allowing you to pull the existing
zone over and avoid retyping or whatever.
After copying the zone, you swap Seconary to Primary or old
Primary to Secondary manually.
At some point you make sure the Primary is DYNAMIC for
the zone so that the DCPromo will work and so that later
Active Directory will be able to use the zone correctly.

Is there a "flag" or checkbox that will tell me the "dynamic" status?

Scrap was a pretty harsh term... I should have said just create a NEW DNS
server on the AD, DC then point all of my clients to the NEW dns, and just
let it rebuild on its own.

Where is the "dynamic" status indicated?

Right -- and I wasn't criticizing the term just pointing
out both this (the migration) or even the retention of the
original DNS is possible if you choose to move the
Primary to the DC.
Even BIND or NT DNS servers can be secondaries.
(Watch your version for BIND & service packs for NT though.)

On the main tab of the Zone properties IF the
zone is a Primary or Active Directory Integrated
DNS server for THAT zone.
Secondaries and Stub zones do not have the ability
to change the zone so dynamic settings would be
irrelevant for them.
