DNS PTR records and Replication

[nick]

Archived from groups: microsoft.public.win2000.dns (More info?)

We have 2 DNS servers, but when i create a record and select to added
an associated PTR (Pointer) record it doesn't do it. i have to add
these manually.

Does anypne know why?

Also the only replication that occurs between the 2 DNS servers is in
the forward lookup zones. No relication at all occurs between the
reverse lookup zones.

Can someone help

TIA

Primary is on a Server called ELROND
Secondary is on a sever called FILEPRINT????

so is there no way of replicating what is in the reverse lookup zones
on the ELROND DNS SERVER to the same reverse lookup zones on the
FILEPRINT DNS SERVER

Thanks

Which is the Primary? Which is the Secondary?

Replication for each is SEPARATE. There is NO
(technical) connect between a Reverse and Forward
zone.

All such (apparent) connections are human interpretation
(e.g., we know the machines in a particulary zone mostly
happen to have addresses in the same Reverse zone range.)

Absolutely, is the FILEPrint server's reverse zone
set to use ELROND server as the "master"?

How do i check that?

What happens when you then manual "refresh from
master"?

Just Refreshes and does nothing else...

If the above doesn't fix it, take a look at the SERIAL
number on the SOA record (in the zone properties is
easiest) and see if the Secondary is (incorrectly) higher
than the Primary.


If higher, a secondary will not copy. If that is the
problem it is probably easier to delete and recreate the
zone giving Primary-ELROND as the master (again.)

Serial Numbers under the SOA tab

Look on the Zone properties (right click) in the MMC
(connect to that particular server of course.)

Well, are you IMPLYING they are wrong after the
refresh (that is the replication)?

Also look on the Master (in this case ELROND) to make
sure it PERMITS zone transfers to the IP of FILEPRINT
(or to all, or etc.)

Herb, this DNS setup is complete screwed up... Why did i get give this
task ... arrgghhh

When i create a new Zone on the ELROND server, Dynamic updates
defaults to NO ans there is only one Name server entry under the Name
Servers tab, which says to me that somebody has missed some config
somewhere?

any ideas

And voila, it is now replicating when i click refresh... Herb your a
great help....

BUT I give up with the PTR records..

as when i create a new host in the forward lookup zone

ie 172.30.100.20 and select the "Create associated PTR record" check
box

it does not add an entry in the reverse lookup zone
"100.30.172.in-addr.arpa.dns"

one minor problem

We will help. You will learn.

DNS is NOT hard but it can require PRECISION at times.

So add the other one by name or IP.

Or did it from another machine. The MMC is in NO WAY
the authority on the DNS servers -- it is merely a tool, where
you can look at one or more DNS servers, but you may have
to ADD them to get started.

If you are really stumped, you can call me. Numbers on

Ok, since Reverse zones are not really important to
most INTERNAL zones -- they are important for
things like external Mail servers usually.

But notice that Reverse zones are PRECISELY like
the Forward zones in the way that you MANAGE them,
but they are COMPLETELY unrelated to the forward
zone(s) technically.

All such relationships are in the minds of use humans.

Did you create the Reverse zone on that server yet?
You cannot create the record in a zone that does not
exist.

> it does not add an entry in the reverse lookup zone
> "100.30.172.in-addr.arpa.dns"

That zone is misnamed: there should be NO ".dns"
on the end of the zone name -- that is FINE for the
FILE name which holds the zone but not for the
zone, which should be:

100.30.172.in-addr.arpa.


Is that (same) DNS server PRIMARY for the zone?

Or, CAN you add it there manually?

> one minor problem

Maybe you hit send by accident without finishing -- I
used to do that a LOT <grin> by leaving the Pointer
over the Reply button in OE which turns into the
Send button on a NEW message.
