Cannot connect to internet, The dns server isn't responding

Hello,

 

This is the second system I have seen in the past two weeks with this issue, I reloaded the OS on the first one.  The system is Windows Vista Ultimate x64.

 

Here's the problem.  Opening Internet Explorer 9 on a Windows 7 PC you get the message:

 

Internet Explorer cannot display the webpage

 

Clicking on Diagnose Connection Problems you get the following:

 

The DNS server is not responding

 

Viewing detailed information your told to contact your network administrator (that's me - no other XP or Windows 7 PC on the network has a connection issue).

Below that is the message:

 

Your computer is trying to use a DNS server that is incorrect or doesn't exist.

 

Note that this is a laptop that started out on another network with the same problem.  I took it to my office to troubleshoot.  My DNS server is a WIndows 2003 SBS server.

 

Below that is an etl log file that you cannot open (notepad sees it as junk, lot of use that is).

 

Steps I have done to try to resolve the issue.

 

Scan system for viruses

There was no hosts file, I recreated that.

Set static IP and DNS.

I can ping the DNS server by IP address, but not by name.

I set the DNS address to 208.67.222.222

Rolled back network drivers

Reininstalled all network drivers

Disable Microsoft Virtual WiFi Adapter

 

Any suggestions would be helpful.
