Hi,
I have a problem with nslookup query; I have a Windows 2000 server that is
DC, when I run nslookup I see this Error:
Can not find name server for address xx.xx.xx.xx(this is the ip of server)
Non-existent domain.
Default name server: something.example.com (I have no idea who is this
domain, I think this is our previous ISP)
Address:81.17.3.2 (the ip of the above name server)

This is some additional info:
On the property of tcp/ip I did point the server to his own DNS.
On the property op tcp/ip has the ip of 81.17.3.2 as the preferred DNS
In DNS consol under reverse lookup I see 4 zones, and one of them pointing
to my DNS.


Any help would be appreciated,

Shahin

Actually I believe the exact wording of the message is
"Can't find server name for address <dnsipaddress>" This is an Nslookup
message saying it has performed a lookup for a PTR on the IP of the DNS
server's address, and it cannot find the PTR because it does not exist.
Create a reverse lookup zone and PTR for the IP of the DNS server and this
message will stop.

What is worse is the next message, in an Active Directory domain environment
you should not use an ISP or other external DNS address (such as a router's
address) in TCP/IP on ANY member of an AD domain, on any interface.
Default name server: something.example.com (I have no idea who is this
domain, I think this is our previous ISP)
Address:81.17.3.2 (the ip of the above name server)

Remove the ISP DNS from TCP/IP.
 
from the command prompt type:nslookup/?
if you want to check the IP address type:ping/?
for example , my ip address you type:ping 127.0.0.1
then enter.
 
Here's my problem. When I run Nslookup on my DNSserver (windows 2000 server)
it comes back with the following:

*** Can't find server name for address 192.168.0.10: Non-existent domain
Default Server: pmgen01.pm
Address: 192.168.200.11

Basically, its not finding my DNS server and defaulting to DNS server of ISP
.. How can I fix this to default to my DNS server (192.168.0.10) and why can't
it find the server name for 192.168.0.10??

And as i said i have a PTR on DNS server.

Let me add that when i ping FQDN of server i get this:

ping nts.exmple.com
replay 169.254.183.93
Why this IP? and i have to tell this server has 2 net work adapter and i use
one of them and other is not in use.

Just leaving the adapter disconnected is not enough, it will still obtain an
APIPA number which is what it is doing. YOu have to specifically disable the
adapter to prevent it from using the APIPA number.

You obviously don't have a PTR for the 192.168.0.10 IP address.
