Just ran into this, it's a windows patch that causes this. After digging around it was kb951748, after I removed that the dns resolution worked again.

Glad to see someone mention this one. I thought of this after I sent this message this morning, but haven't had a chance to try it yet. Thanks!

The few times I had symptoms like that I had to run a winsock reset to get the machine working again. I could run dos tools all day long but as soon
as I tried to use IE or Firefox, nothing would work.

From a command prompt, type "netsh winsock reset" and then reboot.

Info from NETSH Help

Remarks: Resets Winsock Catalog to a clean state.
        All Winsock Layered Service Providers which were previously
installed must be reinstalled.
This command does not affect Winsock Name Space Provider entries.

Subject: [tech-geeks] DNS and internet resolution...anyone seen this?

I've got an issue on one machine that is about to drive me crazy. We've had
some issues with connections, dns, etc, but are working through those.
However, even when everything is running well everywhere else, I have a machine that when you do an nslookup it resolves just fine (beautifully in fact) however when I try and go to any EXTERNAL webpage, it simply wants to point back to the main webserver. I'm so confused on this one. Anyone seen
anything like this or have any ideas?

Thanks,
Chris
