Re: DNS Redesign Issue



Inline
After I create the new AD primary zone in the
child domain, deligate athority, and create the static records, do I want
to
set the new child domain DNS server as primary for the domain controllers?

-If you are going to create a new AD Integrated Zone in each child domain,
then Yes, make sure that each DNS DC points to itself under Nic Preferred
DNS settings. Also make sure that each child domain can resolve the TLD
domain and the _msdcs.domain.tld at the Root domain. This can be done by
several types of configuration, I already gave you what I think that would
be the the best In My opinion.

What about all the AD created records in the company.com domain? Should I
run netdiag /fix and restart the netlogon service to recreate the records?
you can do that or stop and start the netlogon service, you can run dcdiag
/test:dns to check if dns is Ok.

(You had mentioned forwarders previously, but if the network connection
fails
there will be issues.)

There're many pp that like forwarding (myself incl.), however if the link
drops, than you're not able to resolve anything at the root because you
can't connect to the servers.

I think I have my question answered in that I will have to manually create
at
least some of the records, not a problem. I just want to clear up one
more
thing before we close this thread.

Currently all domain controllers point back to the TLD for either their
primary or secondary DNS. This is because tbe TLD DNS server is the only
writable NDS server right now. After I create the new AD primary zone in
the
child domain, deligate athority, and create the static records, do I want
to
set the new child domain DNS server as primary for the domain controllers?
What about all the AD created records in the company.com domain? Should I
run netdiag /fix and restart the netlogon service to recreate the records?
(You had mentioned forwarders previously, but if the network connection
fails
there will be issues.)

Thanks,

-Why you want to export the Zone? The records are automatically created
as
long as you allow Dynamic updates?

-Using DNS console you can right-click the zone and export to a File,
however with this exported file you can't create a zone.

-To export a Zone and import that Zone in another DNS Server you need
to use
Dnscmd.

-C:\Dnscmd ServerName /ZoneExport child.domain.com Filename.dns (this
file
will be automatically created in DNS folder under System32, the File
must
have a .dns EXTENSION, the other problem with this is that you might
need to
change some information on that file, like for example the SOA owner,
and/or
the NS records, then you copy that file to the other DNS server, you
can
start by creating a new Primary zone then you have the option to give
the
name of the file that contains)

Attention you can only export and import a zone if that zone will be
equal
in the other DNS server, although you can export information to ONLY
PART
(like a delegation) you can't use that exported file you can't create a
zone.

*Using the Dns console:

Right click the zone that you want to export and choose the option
export
list, save the file "Test01.txt".

(Open the file and check the format)

*Using Dnscmd

Dnscmd ServerName /ZoneExport child.domain.com Test01.dns

(Open the file and check the format)

-Compare both...

Now the real question here is why do you want to do that??? There's no
need
to have all this work, DNS can dynamically register this records if you
allow it to do so. If you're concern about some manual created records
you
can export the zone using any of the above commands, and then just
create a
script with Dnscmd to create them automatically.

Dnscmd [ServerName] /recordaddZoneNameNodeNameRRTypeRRData

From another news group:

From your description, my understanding on this issue is that you
would
like to change the current DNS design and create AD integrated zone
for
each subdomain.

Unfortunately there's no efficient way to extract the domain
information
for dallas.company.com from the company.com zone. However, if you are
using
DHCP, clients should be able to dynamically and automatically
register/update records with the configured DNS server, and you don't
need
to manually re-input everything.

Considering the current situation, we suggest you follow the
guideline
below:

1. Delete the current dallas(.company.com) and other subdomains on
DNS
server in the root domain
2. On DNS server in the root domain, delegate dallas to DNS server in
the
child domain
3. Create a child zone dallas on the DNS server in the child domain
4. Configure all clients in the child domain to use DNS server in the
child
domain as Primary DNS server
5. Add the parent (root) DNS server as a forwarder on the child DNS
server.

This is great information and I understand all these concepts but I

you
are missing the point of what I am trying to do. In my top level
domain
I
have one primary zone for company.com. That zone contains 9 sub
domains
(dallas.company.com, detroit.company.com, la.company.com, etc.) I
want
to
delegate these domains but first I need to get the information out
of the
tld
zone and into the primary zones that will be created in the child
domains.
If it were possible I would want to "cut" the Dallas folder from the
company.com domain and paste it as the root of the child primary
domain.
I
want to do this for all 9 sub domains. However this is not possible
so I
want to find the easiest way to do it without recreating all of the
DNS
records.

Hi again
Looks like you're out of sync so:
I'm going to try to provide you a solution (but remember you can
have
different implanted solutions to achieve the same thing), if you
desagree
with something please let me know.

You've 1 top Root Domain and several child domains.

You want to design a DNS infrastructure for all domains.



-Objectives are: availability of the name resolution for all
domains in
the
forest, reduce administrative work configuring them, reduce the
Replication
traffic.

-Ok, assuming that you've all DNS servers in DCs (Why on DCs,
because
you
can benefit in terms of security, you can integrate it with AD,
provide
you
less admin work and you can use replication to replicate the zones
for
existent DNS server in your network):

-Generally the Root Domain is used only for administration; I
don't
know if
this is your case, but generally the top root domain has few
information on
it, and is rarely changed in terms of changes, let's begin:

1-Using Stub zones in the root or child domains isn't generally a
good
idea,
why? Well Stub zones do not remove the requirement for
delegations,
Stub
zone data doesn't transfer during zone transfers like delegation
information
does, so if the parent zone is transferred without delegation
information,
how will server find child zones?), So configuring Stub zones
aren't an
option here.


-In the Top Root Domain you make the domain.tld and
_msdcs.domain.tld
AD
Integrated. Because you only have Windows 2003 in your forest make
sure
that
you have your FFL at Windows 2003, Why? - Because among other
things
you can
benefit with replication (only changes are replicated). Next
configure
delegation, delegate each child domain to the correct server(s).
Configure
the replication scope of the Top Root Domain "domain.tld"and the
"_msdcs.domain.tld" available across the forest. Why? - Well First
we
have
availability, even if the link is down the name resolution works
because all
servers have a copy of that zone, including other CHILD domains NS
records,
so the servers can resolve the other child domains even if the
link
with the
Top Root is down, Second we have less Admin work, because the
zones
will be
transferred without any additional configuration, Third the
_msdcs.domain.tld contain information about Global catalog and
other
domain/forest important records and they only exist in parent
(root)
DNS
server (this zone contains information that IS ONLY AVAILABLE IN
THE
ROOT),
so is always a good practice to replicate the root
_msdcs.domain.tld
across
the forest.

- So why not Primary Zone? - To much configuration to be done, is
un-secure,
you can't benefit of AD replication, to use it in child domains
you
would
need to allow zone transfer each time that you add anew DNS server
(which
represents more admin work).

- So why not Secondary Zone? - Well to have a secondary zone you
must
have a
Primary Zone then you must configure that primary zone to allow
zone
transfers (more admin work each time that you add anew DNS server)
and
BTW
Primary Zones are not secure as AD Integrated Zones, But Wait a
minute.
We
can have AD Integrated Zone, and configure other DNS Servers with
Secondary
Zones. Sure, but you still need to allow Zone transfer each time
that
you
Add a new DNS server (More Admin Work), so why not use Replication
and
leave
all Admin work for Windows, and we never have to worry about
configurations
and stuff like that.

What About Internet Resolution? Well we have Forwarding for that,
you
can
benefit of Forwarding to allow Internet resolution in each domain.

Top Root is done.

Time to Child Domains:

-Child Domains: well because we already have the domain.tld,
_msdcs.domain.tld and all forest delegations in the DNS server(s)
across the
forest, this means that the child domains can resolve all existent
domains,
GCs, Existent Sites configuration, etc. So now we only need to
configure the
child zone itself, nothing more. Make it AD Integrated, configure
the
replication scope to All DCs in the DOMAIN, and you're up and
running.

I agree. The question is how to get the domains for the child
zones
out of
the single existing zone for company.com. You can't simply copy
and
paste
it, and recreating all the records would take hours. And I
don't
want the
whole company.com domain replicated to all the child domains.
