The NIC fails	■ If the NIC fails the Group 3 diagnostic test, be sure that
diagnostic tests.	the test is set up correctly, that the NIC is connected to
	an inactive, properly cabled network, and that an echo
	server is set up on the network.

■Replace the failed NIC with a working NIC.

Run the diagnostic tests again, using the same option settings as those used on the failed NIC. If the working NIC passes all tests, the original NIC is probably defective. For information on product repair, see Appendix B.

■Install the NIC in another functioning PC.

Run the tests again. The first PC you used for testing may be defective if the NIC passes the tests in this PC.

■Remove all other NICs from the PC and run the tests again.

If the tests pass, the other NICs may be causing contention. Check the configuration settings. Change the settings if they conflict with another device. See Chapter 5.
