gI work in a windows domain and connect via wireless on a Lenovo T6op running
XPSP2. When at work, I have no problems. When I leave the domain, I cannot
resolve names, I cannot browse or send email, Skype works.

Troubleshooting reveals that I can ping IPs and load websites that do not
require name resolution. Ipsconfig shows that I have an assigned DNS server
that I can ping. Overriding the DNS servers in the network adapter does not
help.

Lastly, loging into my notebook as administrator does not fix the problem.

Any help appreciated.

Do this command: nslookup and then yahoo.com. Do you see any errors?

Hello, Thanks for the great suggestion. I was able to get out of the domain
today and try this test. If you run nslookup, it says: can't find server name
for address 192.168.1.2, no response from server, default server unknown
address 192.168.1.2.

192.168.1.2 is, of course, the ip address of the DNS server and DHCP server
on our domain, the SBS 2003 server.

How do I get the laptop to use another name server?

You may want to add the PTR records. This troubleshooting may help.

You've got me foxed there. How will the laptop read the domain PTR record
when it cannot contact a DNS server?

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.

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?

I apologize for not being clear.

When the laptop leaves the domain, it cannot resolve names. NSlookup gives
the wrong result. As I posted previously, at your suggestion, I tried the
nslookup command outside of the windows domain. The result show nslookup is
trying to use the windows domain 192.168.1.2 even when that name server is
unavailable.

I thought the problem would be solved by getting nslookup to use the name
server provided by the ISP. Presumably if nslookup resolved to the IPS name
server, the laptop could resove names and would allow internet browsing? In
this sense nslookup is not working. If this is not the solution, what is?

Thanks for your help.

I suppose one relevant question is, when you leave the domain, how do
you connect to the Internet?

In your original post, you wrote that you have an assigned DNS server
that you can ping. What is the IP of that DNS server? Is that an ISP's
DNS server? Or is it still 192.168.1.2? And if the latter, how can you
ping it if that is the SBS server in your domain but you're not
connected to the domain?

What does ipconfig /all show when you are *not* connected to the domain?
