There doesn't appear to be anything wrong. What is the issue you're trying to correct?

Like I said, I get the same kind of response.

C:\>nslookup
*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Default servers are not available
Default Server: UnKnown
Address: 192.168.0.1

sure doesn't look right to me. If I type nslookup on either my internet connected laptop or my workstation connected to the forest I get a proper response which is the listed dns server.

srinu it would appear to me that you have yet to configure a DNS server on your lan. Just giving a name to your server doesn't do it.

Wanderer2, that would depend on exactly what kind of network we're dealing with here. I guess that should be the next question. :)

It would appear we are dealing with a ip network.

I think you may find your nslookup results are based on having a gateway entry listed as your dns server vs my results which in both cases list dns servers specifically.

What do you mean "IP network"? This is a private IP address, so it's coming from a local DHCP server of some sort.

Of course it's a private ip. We don't know if its dhcp or statically assigned. It is still a ip network and the answer was to address your question as to what type of network it is.

Is your nslookup command working now?

Actually, I was thinking more along the lines of workgroup, domain, etc. ;) Obviously, it's an IP based network.

actually i have assigned static ip to my system and that static ip is also a dns server ip .

i have created a test lab for my project puropse. while i am typing in my domain

c:\nslookup
server name: hstsrv012
IP address :172.15.2.1

but in my testlab environment its not giving like that format.so what are the reasons for that occurence...

i tried the commands like ipconfig/flushdns and ipconfig/registerdns.but no use.

reasons for that occurence:

In dns you don't have a host entry for the server
you don't have that dns server designated in your workstation tcp/ip properties
due to routing you can't contact the dns server

There may be others that don't come to mind.

Might want to do a tracert to your dns server.
