Re: Cannot Resolve Names Outside Windows Domain

What do you mean "nslookup does not work correctly when I leave the domain"? If you don't connect to the domain, which DNS you will use?

Thanks for the info. I did read this and other articles at your site. Please
help me think through my understanding.

nslookup works properly when I am logged into the windows domain: Default
server nameofserver.nameofdomain.local, Address: 192.168.1.2

nslookup does not work correctly when I leave the domain. It still points to
the domain server on the windows domain, the ip address, but the name is
listed as unknown.

You diagnose the problem as the Reverse DNS is not set up correctly on the
windows domain. If it was set up corrrectly, my laptop would be able to get a
hold of the available DNS servers on the ISP outside of the domain.

I am correct in understanding your help? It seems counter-intuitiive to me
that a problem on the windows domain (where my laptop works fine) is
preventing my laptop working properly outside of the domain.

Thanks again for your help.
