I have a customers computer that cannot connect to the internet via the local area network. The pc has access to the shares but connection to exchange emails in outlook and internet browsing have stopped working. i have reset netish int and winsock. I have tried replacing the cables. restoring back to previous system point but with no luck. There is also no flashing green light on the network card in the pc only a dim amber one. cannot ping google.com but can ping the default gateway. There is no firewall installed.
