Last night on all the computers on our home network windows update downloaded and installed something. (Windows XP Pro)
This morning I have basic http access but not websites like external mail servers, Vbulletin forums. Antivirus update can't connect, can't play online games (on release day of Wotlk as well!) It is the same for all the computers.
The only thing that has changed on all computers is the windows update and restart overnight but I'm not sure what that could have done.
I'm with Virgin Media, they say all service is running normally.
I am using a router, have reset the router, and the modem.
Network Diagnostics says
"Windows did not detect any problems with your Internet connection over HTTP and HTTPS but was not able to make a successful connection over FTP. The most likely cause of this problem is that a firewall client running on your machine is blocking necessary FTP ports."
So I turned the firewall off completely and there is still no change, I've disabled AVG in case that was doing something, and no change. I have checked restricted sites in IE but as it is stopping games and other connection issues I don't think it is that. I have done a system restore to when I know it was working and tried working in safe mode - no changes.
Can anyone help please? :(
