Ping Replies with the root domain instead of the child domain

Hi all

We have windows server 2003 DNS and tree DNS zones in it. Since we have three domains, we created three zones, one for the root domain, and one for each child domain.
The problem that I am having is that I am getting replies from computers in the child domain and showing that they are in the root domain like this: when I ping this computer I get this reply:

I went to the DNS and saw that the computer is in the correct zone, then went to AD and saw that the computer is in the correct child domain.

Is this a normal behavior or we have a problem?

On the PC's what is configured for their primary and secondary DNS server?  They should have only one entry pointing at the child domain dns server.

What IP address are each of the zones listening on....?
I would think that this is normal.  What happens when you use NSLOOKUP instead of ping.

NSlookup shows that they are in the root domain.

one thing I remembered from Mazaraat comment; is that both DNS server are in the root domain.

will that be the reason?
and if so is there any that we should do to avoid any kind of issues?

There are many different ways to configure DNS.  There is no right or wrong way to do it...what ever works for your environment is fine.

In your child domains, do you run DNS?  I would assume so.  For example, you might have installed each DC, also as a DNS server.  To check this, look at the TCP/IP settings of you DC's.  Do they point to themselves for DNS?  If they do, they are probably running the DNS server service.  Also, you can check to see if they are running the DNS server service.  In most environments, your DC's will also be the DNS servers.  However, this is not always true.

Remember this basic guideline for TCP/IP settings of your DC and clients:

Server Name: ServerDCDNS1
Subnet MAsk:
DNS: or  (Don't point DNS server to ISP DNS servers)
DNS2: <next closest internal Windows DNS server> or <empty>

Client NAme:  Desktop1
Subnet MAsk:
DNS2:  <next closest Windows DNS server...never point to ISP DNs servers>

Also, check the DNS suffixes of your clients and servers?  Print these out so we can see them...

I am not sure if that would do it, but we have 12 DCs, and they all point to the two DCs in the root domain even though they have DNS installed and running on all of them.

Thanks a lot
