nsloookup doesn't show a default server

I am a newbie to some of the networking items that so many of you have known for years.

I have a new SBS2008 server. When I go to the command prompt and type nslookup the program responds with
 "Default Server:  UnKnown"
How do I tell nslookup that I am on the DNS server?

Hey,

All that means is that it failed to find the server name when looking up the IP Address. It's the equivalent of:

nslookup 1.2.3.4

Where 1.2.3.4 should be replaced with the server IP.

You can fix it by ensuring a Reverse Lookup Zone exists for your subnet (like "192.168.1.x Subnet" or 1.168.192.in-addr.arpa depending on your view options) in the DNS Console. If it does, verify that a PTR record exists for your server.

This is weird! There must be something very simple and fundamental that I missed in set-up, Could you assist with this? This command was run from the server with both admin and non-admin privelage, both returned the same result.

C:\Users\serveradm>nslookup 192.168.2.1
Server:  UnKnown
Address:  fd30::9631:b7f6:e3da:603d

*** UnKnown can't find 192.168.2.1: Non-existent domain
Hi,

if 192.168.2.1 is the dns server, type nslookup server 192.168.2.1

that will tell it to use the dns server as the default lookup server, and it will test to see if the dns level connectivity is present in the TCPIP stack.
