I have 3 computer attached to an ADSL router, two of the computers work fine but on the third I cannot connect to the net or even the router.  
I can ping internet address
It resolves DNS names
I have loaded firefox and it has the same problem
I have flushed the dns
I have tried to go to websites using IP address
I have disabled all firewalls and virus protection
The computer can send and receive email
I have changed DNS server address in TCP/IP address properties as well as setting them to auto.
Windows XP SP3 with IE7 and now firefox.
Any ideas would be apprciated

Last time I saw this... it required DIGGING through the registry and clearing out some rather obscure DNS entries, changing some "0" (false) to "1" (true)...

I couldn't begin to tell you everything that I did. and would even recommend against it, the computer has only 1 or 2 programs on for processing -- no biggy if I had to reinstall.

I'd suggest:
1) roll back SP3 (thats what triggered my issue)
2) If that fails: reinstall if thats an option

(In the end, if it happens again - I'm just reformatting).

Just for the time being I would get rid of SP3 if you can and stick with SP2 and then

Restart if need be then

Right click on my computer --> properties --> device manager --> hardware --> navigate to the network cards section and un install your network card. Then on one of the other computers that works download the latest driver for your network card alternatively you can download the latest driver on that computer before you un install it and then un install it using device manager as above and then install the latest network card driver.

Restart again here if needed which I would suggest as you have changed drivers on the network card.

Then as below do a winsock repair :

Once that is done - restart and try again.

I have this same problem happening on 3 pc's, 2 have sp3 installed, 1 has sp2, also on one of the pc's sp3 was working fine.  These all quit working within the last 2 weeks, I'm not sure if it's an update or what.  I've done the winsock fix, put a new nic in, set static ip's/dns servers, but still this issue.  I can resolve any website, can ping them, can get email, can ftp, it's as if some phantom firewall is blocking port 80 or something.  I uninstalled the antivirus in case that was somehow doing it.  It DOES work in safe mode though.  This is happening on both firefox and IE for me.

AVG has a problem  with resident sheild and the web shield, they have a fix and they emailed it to me. IT wasw called fixfiles.zip. I can't attached it so below is the instructions from the email. If you turn off the above two everything works.

Hi there,

Please right click and save the attached file fixfiles.zip to your hard drive (ie. Your desktop)

Right click on the file on the desktop, and then click Properties.  If you see a button called Unblock to the bottom left hand corner of the screen, please click it, then click Apply and OK.

After this, right click on the file again, and choose extract all. Extract the file to your desktop.

Double click on the extracted file fixfiles.exe

Restart the computer.

Please see if this fixes the issue. If you still have inactive components, please perform an installation repair in this way:

1. Download the latest installation file from this webpage:

http://www.avg.com/download?prd=ais

- When you are prompted, please do not open this file directly from the internet, but click the "Save" button and choose a location, where the installation file should be stored. We recommend saving the file to the Desktop.

2. Please check whether you are logged under some account with administrative rights. For more details, please visit this FAQ:
http://www.avg.com/faq?num=1196

3. Locate the downloaded AVG installation file (it has a four color square icon and its name starts with AVG_...) and launch it.
- Choose the "Repair installation" option and follow the wizard.
- When finished, please restart the computer.

Please contact us if you have further issues.

Kind Regards,
