Diagnostics reports a failure.
Cause Solution
Network controller interrupt is shared with an expansion
board. Under the Computer Setup Advanced menu, change the
resource settings for the board. Check that they are different
from those of the network controller.
The network controller is defective. Disable the integrated network controller from the setup
utility and install a new network interface card.
Network controller stops working without apparent cause.
Cause Solution
The files containing the network drivers are corrupted. Reinstall the network drivers.
The cable is not securely connected. Ensure that the cable is securely attached to the network
connector and that the other end of the cable is securely
attached to the correct device.
The network is temporarily unavailable. Contact the network administrator to find out the status of the
network.

Cause Solution
The network controller is not configured properly. Verify that the computer is properly connected to the
network, that a DHCP Server is present, and that the
Remote System Installation Server contains drivers for the
network controller.
