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.

can you ping an external IP (like 8.8.8.8) if not then its not passing thraffic beyond the gateway, so check the gateway out, if it can ping 8.8.8.8 but cant ping anything by name, then it's DNS thats the problem.

Proxy settings in IE probably wouldnt cause Outlook to not pick up email.

Try Connecting a different machine (may be a laptop) to the same port, that will make sure if the problem is with client or the N/W.

If its a client end issue, try reinstalling the driver after fully uninstalling it.

Hope this helps

Boot that machine to a linux live cd and test net connectivity.
If it works then it narrows issue to OS

What Anti-Virus or Anti-Virus Suite is installed on your system?

Did you try disabling it for a while to test if you able to browse again?

You could also try different DNS servers to make sure its not DNS issue on the system

Please DNS servers and try 8.8.8.8 or 8.8.4.4 and check

After making sure DNS is not the issue by pinging an external IP such as 8.8.8.8 and getting no response.

Replace the Network Card.
