The add-in adapter stopped working without apparent cause: Try reseating the adapter first; then try a different slot if necessary.
The network driver files may be corrupt or deleted. Delete and then reinstall the drivers.
Run the diagnostics.
Cannot Connect to a Server Make sure you are using the drivers that are shipped on the System Resource CD for the
onboard network controller.
Make sure the driver is loaded and the protocols are bound.
Make sure the network cable is securely attached to the connector at the system back panel. If
the cable is attached but the problem persists, try a different cable.
Make sure the hub port is configured for the same duplex mode as the network controller.
Check with your LAN administrator about the correct networking software that needs to be
installed.
If you are directly connecting two servers (no hub), you will need a crossover cable (see your
hub documentation for more information on crossover cables).
Check the network controller LEDs that are visible through an opening at the system back
panel.
