• Check that your computer is properly configured for TCP/IP. See
"Configuring the TCP/IP Protocols" on page 3-3.
• Make sure the correct network adapter driver is installed for your
operating system. If necessary, try reinstalling the driver.
• Check that the network adapter's speed or duplex mode has not been
