dns problems windows 7 netbook

April 12, 2011 at 16:15:44
Specs: Windows 7 starter
I can access a website with ip address, e.g., http://74.125.79.104, but not with www.google.com.
I've checked my tcp/ip setting, and the DNS IP setting was set "automatic". Could anyone help?

In the configuration for "Wireless LAN adapter Wireless Network Connection" look at the DNS server ip address.
I guess, it should be the same address as the ip address of the default gateway.

DNS Servers . . . . . . . . . . . : 10.1.10.1

This is not a valid name server nor does it appear to exist since it doesn't return a ping.

Though you can set dns to your gateway ip it is better if you contact your isp and get their dns servers since they will be the closest.

Then you logon to your router and change the dhcp scope to include the correct dns ip.

Thanks, I'll try that.

I wonder this might be specific to my computer/operating system.
My other laptop with windows 7 connected to the same router/modem works fine.
I borrowed the wireless adaptor from the working laptop to my netbook, and I have the same problem.
Ping to an external ip address works, but ping to the name doesn't work. So it's not the web browser.

Anyhow thanks and will let you know of the results.

paulsep didn't read post #7

uncheck ipv6 in tcp/ip properties and try the nslookup again just in case we have a protocol binding priority issue.

If still no go rename your hosts file to hosts.old
found in windows\system2\drivers\etc

if still no go I have to suspect your tcp/ip stack is corrupt. Web search tcp/ip stack repair and follow the how to.

I followed all instructions and reset the tcp/ip stack using netsh command with no success.
Anything else I can try?
Thanks again for all your recommendations - very educational.

netnanny doesn't alter the tcp/ip stack that I am aware of. It monitors/records what web sites visited, etc.

This is more a sign of malware/virus activity. You should review netnanny's settings to make sure its not configured to block internet access.

So far all of your connections have been wireless. I would suggest disabling the wireless and connect just wired to see if there is a difference.
