HTTP stops working on XP Pro (HTTPS & FTP are fine)

Posted on 2008-11-02

On 3 systems in the last 2 weeks HTTP has stop working completely. When you try to open a HTTP website the standard 'page cannot be displayed' message is displayed, yet HTTPS and FTP sites, and all other network services work as normal.

The 3 computers are at 3 different physical locations, two of them are connected via a linux gateway/proxy, and the third is a home computer connected directly to an ADSL modem via ethernet. One of them has been in place for at least 2 years, one a few months, and the other stopped working less than a week after a reinstall of windows.

Each of the systems is using a different ISP.

They are all XP Pro, one with SP2 and the others with SP3.

I have tried IE6, IE7, and firefox and they all do the same thing.

All systems have AVG Network edition installed

I have tried logging in to a different user account, resetting winsock, reinstalling TCP/IP, running sfc /scannow, manually setting the MTU to 1500 in the registry, running WinsockFix, WinsockxpFix, LSPFix, CCleaner, Spybot S&D, Malwarebytes AntiMalware, a full AVG scan, disabling all firewalls and antivirus, and replacing the network card with a different make/model.

I have run:
   netsh int ip reset reset.log
   netsh winsock reset catalog
at the command line.

None of this made any difference.

Other computers using the same internet connection/modem and proxy where available are all working.

From the effected systems you can ping, and telnet to it on port 80 successfully.

The only solution I have found is to reinstall windows, though I really need another option.

Any suggestions are very much appreciated.

This problem is caused by a bug in AVG 8.0.196

Disabling the Web Shield and Link Scanner will allow you to access HTTP sites again

Once you can do that download the fixfiles.exe utility from, run it, and restart the computer.

***I have found the solution to this problem myself, can I have the points refunded?***

I had the same problem... but when I run the fixfiles.exe... I get a "Nothing to fix." message. I have AVG Anti-Virus 8.0.176 (free version) installed. I have Windows XP SP3.

I also tried the repair installation, WinsockXP fix utility, as well as this following netsh command: "netsh int ip reset". But still nothing. My http is still does not work, while all other protocols - https, ftp, smtp - are functional. Interesting point: HTTP will work for a while when my computer starts up, but stops working after about 5 mins. I monitored registry changes with Spybot during this time period, but nothing gets caught and I don't have anything whitelisted here.

Anyone else out there tried all these and still having http problem?

(I think I've had better luck getting rid of viruses than this issue with AVG.)
