If you have problems, see LAN troubleshooting suggestions (on page 12-5).
Record all network configurations before modifying any existing network configuration information on
the network interface card. Once the network configuration settings are updated, the previous
information is lost. This may cause a problem reconnecting the host computer to a corporate
network, particularly if DHCP Enabled = NO (disabled).
Be sure to return all settings to their original configuration before reconnecting the host computer to a
corporate network. Failure to do this could result in loss of data. Contact your system administrator
for more information.
