DNS - Reverse lookup configuration

SBS Server 2003 configuration question.

Reverse lookup of the local subnet from my workstation to my server fails.
I assume that this is because there is no ptr record in the reverse lookup
zone?

I've got lots of records in the forward lookup zone: the DHCP service
updates DNS records.

Can I, should I, configure something differently so that I automatically get
reverse lookup records as well?
The reverse lookup subnet is "Active Directory Integrated", and Dynamic
updates is set to "None".

Hi David,

It's just that dynamic update option. Change that to Secure Only and it
will start populating as well.

I know I'm not answering your question, however.

From your Previous post it sounds like you have TWO DHCP Servers?
I would Disable the VOIP one let SBS do the DHCP
and manage the IP's From their
Put the Phones on STATIC IPS in a High Range say 192.168.16.200-250
You may not want to put phones in a static IP , but I would probably and
stick a label on the bottom of them.

If you don't understand what I'm saying
Please post exactly the IP range everything is, where is the DHCP etc etc
(IPCONFIG /ALL of the server and PC would be good.)

Sounds like some clean up needs to be done before we clean up things.. ???

And David
Since this is a SBS Server, you really need to post this in the SBS group
(So we don't have to bother the other guys

I don't have any control over the VOIP network or the hardware -- I just
try to clean up the Windows Server.

I think that some of the DHCP questions are left over from a 'test'
VOIP configuration, but I can't/won't change things I don't understand
-- and the fury that comes down on a sys admin who crashes the
server is nothing to the fury that would descend on me if I crashed the
phone system.

thanx,

If there are two DHCP servers, and one is updating DNS, and the other is
not, then I can understand why you do not have the necessary PTR record in
your reverse zone. As long as it remains this way, well, it will remain this
way.

I think you're worried about what your manager/boss will say, but you
apparently know there's an issue. Have you compiled a report for your
manager with your findings, along with recommendations to fix the problem? I
mean in any environment, there should be some sort of communication channel
that allows administrators who find problems to report such, as well as make
recommendations without getting their heads bitten off. If not, it would
appear to be a challenging environment to work in.

OK, I've enabled secure updates of the reverse lookup zone.
This seems to be working, and when I do NSLookup the server
now knows what it's name is.

There are still a lot of things missing from the forward zone,
(windows 98 and linux workstations) so I'm waiting until
some DHCP leases expire to see if that helps.

There are also a few unexplaned values in there. I've turned
on scavenging, but that hasn't had any effect yet.

David,

Waiting for scavenging won't register them. To get machines that can't register themselves such as Win9x machines, and Linux machines that are not configured with the zone name that you want to register into, simply set DHCP Option 081 (the DNS tab in DHCP Properties), to register everything that can't register themselves (the bottom button).

Make sure that in DHCP Option 006, that the DNS servers are only the internal ones. No external, no ISP, etc.
