Re: DCDIAG DNS Failure

Sorry for not posting sooner, but was under the weather for a few days. I
seem to have solved the error by doing the following:

1. Adding a ptr record for the loopback address in the reverse lookup zone.
2. Having the DNS server point to the loopback address instead of hard
coding its own ip address for the preferred dns server. (Clients still point
to server ip address)
3. I cleaned up the extra zones referring to the loopback address

Thank you again for your response and help.

Ok

so the sddcsrv03 is a DC and DNS server right?

Correct

and the errors are accouring in this server correct?

That is correct, although I receive the same error when dcdiag is run
against the child dc.

the NIC properties looks ok.
Make sure that under TCP/IP properties you have the option "Register this
connection's address in DNS" selected.

It is selected.

check if the Shiprepair.com dns zone allows dynamic updates if the zone
is
AD integrated select secure updates only.

It is.
instead of having 1 Reverse lookupzone for each subnet:
192.168.0.x,192.168.1.x, etc, create ONLY 1 reverse lookup zone only but
like: 192.168.x.x.
- rightclick the DNS server and clear the cache.
- run from cmd: ipconfig /flushdns
- run from cmd: ipconfig /registerdns
- restart the netlogon service.
- run netdiag /fix

I will perform this later today and look over the articles you listed
below.

Thanks for your help.

Then check if the records were created for the reverse and Forwarding
zones.
Run the tests again and check if the problem remains, if yes you might
try
to recreate the zone for Shiprepair, check these articles that migh help
you

Ok

- can you post here the results for ipconfig /all of your DNS server.
- also can you check if the DNS server is responding to all its
IPAddress
(DNS Console->right click->interfaces tab.
also describe (can be other different names) your actual reverse
lookup
zone
and forward zones.

- these are loopback related, don't worry.

So, with advance view I have 4 forward lookup zones and 10
reverse
lookup
zones. Without advance view I have 4 forward lookup zones and 7
reverse
lookup zones.

- are you hosting 4 different domains?
domain01.com, domain02.com,etc?
did you created MX records for the exchange domains that you're
hosting?

The domains are valid. I have created an MX record for the exchange
domain.

- 7 reverse lookup zones?
do you need all these reverse zones or your DNS server is
multihomed
(multiple NICs)

My DNS server is not multihomed. Everything certainly worked better
after
the reverse zones were created. They are all valid reverse zones.

-Your exchange server that is giving you problems, can it send Mail
outside,
or the problem is only to receive Mails?
if the problem is only to receive mails, check that your FW/ROUTER
have
the
correct ports (SMTP 25TCP) pointing to the exchange server, also
make
sure
that the FW/ROUTER for your domain has the correct public address.

The router has the correct info. The problem is mainly slow
delivery,
not
so much non-delivery of incoming mail.

-If the problem is between the Exchange 5.5 and 2003 you should
check
the
connectors between them, goto exchange ng they can help you out
better.

I am in mixed mode right now with both ek55 and ek2003. I will post
in
the
exchange group, although I would like to correct the DNS error found
in
dcdiag.

Ok, disable the advance view on DNS console, what do you see
now?
No zones?
If yes then you can configure one zone, make AD integrated (If
the
server
is
a DC), run ipconfig /registerdns

I still see zones after disabling the advance view (Expected?).
The
only
change is I no longer see 3 of the reverse lookup zones. They
are
as
follows:
0.in-addr.arpa
127.in-addr.arpa
255.in-addr.arpa

So, with advance view I have 4 forward lookup zones and 10
reverse
lookup
zones. Without advance view I have 4 forward lookup zones and 7
reverse
lookup zones.

Jorge,

I have looked at most of the articles you sited and I have
configured
DNS
accordingly sometime ago. My clients are pointing to my
internal
DNS
server
only. The DNS server lists only itself as the preferred
server
with
no
alternate. I am not certain about the reverse lookup zone
setup
as
I
have
3
entries that seem to refer to the loopback address. I'm not
.
