Baffling DNS Problem

Woke up one morning to find that both my internet browsers (IE7 and Netscape
7.2) were not loading any web pages! Narrowed it down to a local DNS
problem. I am running Windows XP Home Edition SP2.

Here's what's been established:
- I can connect to websites with IP addresses but not by their DNS server
names (tested with google.ca and others)
- Same result when 'pinging'
- Network Diagnostics for Windows XP also states a DNS problem in the log
(see below for full log)
- cable modem and connections are all in perfect working order (IP and DNS
addresses are all okay from ISP point of view)
- internet connection works just fine when switched over to my MacBook
- no virus or spyware detected (my antivirus software is current with latest
virus defs and AutoProtect enabled, I also have Windows Defender and Spybot
for spyware detection)

Things I've tried:
- repairing/renewing IP address
- flushing DNS
- reinstalling network drivers
- removing Winsock/Winsock2 from Registry and re-installing Internet TCP/IP
Protocol
- System Restore
- deleting all temp Internet files, cookies and history

Unfortunately, that's the extent of what I know to try, all to no avail and
I have a feeling reinstalling IE7 isn't the answer because Netscape has the
same DNS error. How do I fix this problem without resorting to try
reinstalling Windows XP? HELP!
