I ran a defrag a few days ago on my desktop machine and I can no longer connect to the internet.

I have performed the following tasks and still no solution...
-adaware (clean)
-spybot (clean)
-Norton's full scan (clean)
-cc registry cleaner (clean)
-updated all drivers
-reset modem
-repaired connection
-ran "WinsockXPFix"
-confirmed modem operation with laptop (connected fine)
-uninstalled/reinstalled onboard LAN device
-installed FireFox as an alternative (no connection)

System specs...
Windows XP Home SP2
ASUS K8V-SE Deluxe
AMD 64 3400+
3x 512DDR
GeForce FX 5950 Ultra

Please help!

Can you ping google.com? Try to to ping 4.2.2.1. Can you reach that? If you can, do you have AVG installed? If so, run msconfig, uncheck all the AVG items on startup, reboot, connect to the internet?

I'd but money AVG is your culprit. Why? No idea, but the problem happened with 2 of my computers here and uninstalling and reinstalling AVG fixed it. Still looking for an explanation. Anyone have one?

You say you can not 'connect' to the internet, but your pings show you are connected. What is actually the problem, can you not resolve DNS or?

Any time I attempt to view a webpage, I receive "cannot display the webpage" error.

In IE, do you happen to have another browser installed you can try. Can you ping names at a cmd prompt by dns names (e.g. can you ping www.google.com, does it resolve?)
 
Ok, looks like the problem isn't connectivity it's DNS. If you do an ipconfig /all what dns servers are configured, are they valid?

Frankly I would have thought the winsock reset would have fixed this, I really suspect the problem is still there. Exactly what tool did you run (version #, source, etc) to reset winsock?
 
Are other machines on that same network working correctly (e.g. have you ruled out the dns server as the problem)?

Yep! My laptop is what I'm posting with. I've conducted the pings with both machines.
 
I have reset the TCP stack via "netsh int ip reset resetlog.txt"

I also installed the exported "good keys" on the site you linked.

Still no avail.
 
Its possible one component in the stack got corrupted. At this point I'd do a repair install over your existing install (your settings will be kept)

Yea. If resetting winsock isnt fixing this, the component which actually does the dns resolution may be corrupt. A reinstall will rule that out (or fix it)
 
Windows Repair option did the trick....for now. I can browse just fine, however, during the repair, I was notified that several files were not found. Hopefully, they will not cause any further issues.

Thanks for all of your help folks!

Good. If you find out what the exact cause was update the thread please.

AVG is an antivirus program that caused a similar problem on a few of my machines the end of last week.
