Got a problem on my girlfriends laptop.

IE6 connects to internet fine, but no other software will - Firefox wont connect, and the anti-virus cant connect to update (AVG)

It first happened when I updated firefox to version 2.0. I then uninstalled it back to older version but the damage was done.

I've tried using IP addresses to connect but it's the same so it's not a DNS problem.


So I'm paraying soeone can help us out - it's just so weird that IE can connect but not other software.

( it's not firewall, I've disabled that )

's proxy and restore ideas are good first checks. A common root cause when one client can reach the web but other applications cannot is a system-level networking filter or a damaged Winsock/TCP stack rather than a per-application bug. The quickest way to narrow this down is a non-destructive test: boot into Safe Mode with Networking and try the failing apps. If they work there, a third-party driver/service is likely interfering.

Practical next steps (do them in order and reboot after the reset steps):

Open a command prompt as Administrator and run:

netsh winsock reset
netsh int ip reset resetlog.txt

Then reboot.

Check the system WinHTTP proxy settings (different from IE): on Windows XP use the proxycfg.exe tool in %windir%\system32; on Vista/7+ use:

netsh winhttp show proxy
netsh winhttp reset proxy

If a security product or third-party firewall has been installed previously, fully uninstall it (UI "disable" can leave kernel filter drivers active). Also try disabling startup items with msconfig or test again in Safe Mode with Networking.

If the problem persists, reinstall the NIC driver, try a different adapter (USB Ethernet/wireless) or capture traffic to confirm whether packets leave the PC. These steps will separate a corrupt Windows network stack from a third-party driver problem and guide the next action (vendor removal tool or repair install).

Are you using a proxy server? Have you tried to a system restore to the day before you installed firefox 2.
