I've got a difficult problem that's I've been working on for days. System: emachines running Windows XP Home Edition. OS: Windows XP Home Edition - SP3 - all updates current Connection: Cabled network connection via onboard Intel Pro/100 VE network adapter Router: Linksys Modem: Surfboard This system has been functioning in my current configuration for several years. The current symptoms are that it will boot fine, network diagnostics complete successfully, ping works to local and remote hosts, Skype connects and funtions, Windows Messenger connects OK. Problem: No internet connectivity can be made via a browser (neither IE7 or Firefox) It goes through the connection attempt (resolves IP address), then times out. (Note: several other computers in household share same router and work fine) Background: Problem originated after uninstalling CA Internet Security Suite 2007, uninstall was messy as it did not uninstall cleanly and had to be removed with 3rd party tools. This originally broke all network connectivity, but I was able to restore limited connectivity (would work for only 2-3 minutes after each reboot) by uninstalling and reinstalling the network adapter, then resetting Windows firewall setting to default. I was then able to connect to the internet long enough to use CA's online removal tool that is supposed to remove all traces of the Security Suite and clean up the registry. I also made sure that I have all current Windows Updates, scanned for viruses, malware, and spyware. After additional fix attempts, all internet connectivity was lost. Current state: As mentioned previously, I cannot connect via a browser to any websites. Skype and Messenger still work. Remedies tried thus far: - Updated network adapter driver with latest version, then rolled it back to previous version once it had no impact - Reloaded the CA Internet Security Suite 2007 software that originally caused the problem when removed. Uninstall again failed and I had to work with CA Technical Support to get a utility to completely remove all traces of their software. They then stopped providing support and thought it was a winsock problem. - Reset Winsock via netsh winsock reset command and via WinsockFix.exe - Reset TCP/IP using netsh command - Reset firewall to default settings (Windows firewall is currently off) - Diabled, uninstalled, then reinstalled Network Adapter - Tried different ethernet cable - Reset modem and router - Manually loaded default gateway and DNS servers into TCP IP properties - Tried all steps outlined in http://support.microsoft.com/kb/314067/ - Flushed DNS and restarted DNS and DHCP Services - Downloaded and ran all features of Dial-a-Fix utility - I've also tried restoring to previous restore points, but all restore points prior to the problem have been lost by various fix attempts. I'm running out of ideas and have searched the web for any similar problems, but have been unable to find anything I haven't already tried. I would deeply appreciate any help anyone could provide from this forum. I've attached my most recent Hijackthis log.
