Question : nslookup problem

I have the primary dns server with win2k server.This Primary DNS can solve domain names by using ISP's DNS.
The problem is when I set my dns server on my client desktop to be this ip address of my Primary DNS, I cannot solve the domain name.

The error said something like "non-existing domain" or something like that. What's wrong ? Please suggest.

Answer : nslookup problem

Under "Forward-lookup zones" do you have a zone called "."?  If so, you should delete it.  Also, make sure that the Root Hints list is populated with addresses.  You can also try adding the 203.148.255.77 into the forwarders list and see if that gets things going if the last two suggestions don't help.
