I've spent 2 days on this and am reaching out for help because I'm at a loss.
As the title says, it's only internet internet that's not working. Other computers on the network are not affected & no proxys in use. IP4 only, same issue on different networks with DHCP or a manual address configuration.
This occurred after the KB2809289 update was installed and the computer rebooted. I uninstalled it but the problem did not go away. I am unable to roll back to a prior restore point either, that keeps failing.
I have run with no positive results:
netsh int ip reset & netsh winsock reset
Something that's strange is that when the computer reboots I get a message about "Ruby interpreter stopped working". Even after disabling all startup apps (but not services). I'm not sure where this is coming from; I did a system search for the application name (rubyw.exe) and offending module (msvcrt-ruby191.dll) listed in the error message but the only hits were in Appdata/Local/Temp
Any help or suggestions on where to go from here would be greatly appreciated.
EDIT: Additional Info:
Chrome gives a message: Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error
Firefox gives " Server not found
IE will not open, it crashes without an error.
As mentioned above, DNS is working, If I type in an IP address chrome's error changes to Error 2 (net::ERR_FAILED): Unknown errror. Firefox displays the same Server not found message.
Same results when using Safe Mode with networking
