Hi,This Windows XP desktop PC is connected to the Internet through a dialup connection.The dialup connection connects just fine, but I have no Internet access while connected.Other computers using the same dialup settings are still working great.The owner states the problem began after a computer game crash and subsequent hard reboot.I tried IE, Firefox, Messenger, Thunderbird, etc.All these programs fail instantly when attempting to connect, like they don't recognize that there is an Internet connection.I can ping Internet IP addresses, but I can't ping site names like www.google.com.I cannot connect to an IP address with IE, so this does not appear to be just a DNS problem.This dialup connection uses a proxy server (filter.voicenet.com:8241).I have verified the proxy settings for the dialup connection are correct in IE and Firefox.I have reset the TCP/IP stack.I also ran the Winsock XP fix tool.Norton was installed, but I ran the Norton Removal tool to completely remove the software.Windows Firewall is disabled.No other security software is installed as far as I can tell.I'm open to any ideas...Thanks for your time,Kendall

ICS isn't a proxy server. Remove all proxy settings and see if that fixes the problem.If it doesn't, there's a problem with DNS resolution, as shown by the fact that you can ping IP addresses but not site names. Check the computer's DNS server address. By default, it should be 192.168.0.1 -- the LAN address of the ICS host computer.Boulder Computer MavenMicrosoft Most Valuable Professional

OK, I see I didn't make myself as clear as I should have.Let's take ICS out of the picture. The situation is still the same.Below is an edited (hopefully clearer) description of the problem:This Windows XP desktop PC is connected to the Internet through a dialup connection.The dialup connection connects just fine, but I have no Internet access while connected.Other computers using the same dialup settings are still working great.The owner states the problem began after a computer game crash and subsequent hard reboot.I tried IE, Firefox, Messenger, Thunderbird, etc.All these programs fail instantly when attempting to connect, like they don't recognize that there is an Internet connection.I can ping Internet IP addresses, but I can't ping site names like www.google.com.I cannot connect to an IP address with IE, so this does not appear to be just a DNS problem.This dialup connection uses a proxy server (filter.voicenet.com:8241).I have verified the proxy settings for the dialup connection are correct in IE and Firefox.I have reset the TCP/IP stack.I also ran the Winsock XP fix tool.Norton was installed, but I ran the Norton Removal tool to completely remove the software.Windows Firewall is disabled.No other security software is installed as far as I can tell.Thanks,Kendall
