Domain name gets added when querying a domain name using NSLOOKUP.

Hi, I have a Windows 2003 Server that has DNS setup on it. When I use NSLOOKUP on here and type a domain name such as google.com it comes back with:
> google.com
Server: servername.domainname.com
Address: 172.16.1.13

Non-authoritative answer:
Name: google.com.domainname.com
Address: (IP address of my ISP)

So whatever I am querying it is adding domainame.com to it. I don't know where this is located so that I can fix it. It is driving me nuts. I have looked in the Advanced properties of the TCP/IP under DNS and there is no domain name added there. Thanks in advance for your help.

 

My guess is that your computer thinks it is the only DNS server available. Therefore it is trying to resolve everything against the namespaces that it knows about. You need to remove the root zone from your DNS configuration. Have a look at this article:

How to configure DNS for Internet access in Windows 2000

As the title suggests, it was written for Windows 2000, but is still relevant for 2003. The section to look at is the one called "To Remove the Root DNS Zone ". Once the root zone is removed the system will be able to look elsewhere to resolve addresses that it doesn't hold directly.

It is also a good idea to set up a forwarder (the next section in the article above). This will tell your DNS where to look for addresses outside it's zone. Set up forwarders directed at your ISP's DNS servers.
