Troubleshooting 35

m If you’ve exhausted all solutions, you may need to reinstall Mac OS X Server or NetBoot

server software. If you reinstall server software you will lose documents and data. If you

have backed up your server, you can restore the data you backed up.

Problems With NetBoot Client Computers

A NetBoot client computer won’t start up.

Tr y these solutions:

m Sometimes a computer may not start up immediately because other computers are

putting a heavy demand on the network. Wait a few minutes and try starting up again.

m Make sure that all the cables are properly connected, and that the computer and server

are getting power. See the troubleshooting information that came with the client

computer for more information.

m Check that one end of the Ethernet cable is plugged into the Ethernet port on the

computer and the other end is plugged into a working Ethernet connector.

m Make sure the startup server program is running. If other computers can start up from the

server, the server program is running. If other computers cannot start up, see “Checking

Server Processes” on page 36.

m Make sure you haven’t exceeded the number of IP addresses assigned to your network.

You check the IP address by logging in to the server and opening the Network

Preferences panel.

m If you installed memory or an expansion card in the client computer, make sure it is

installed properly.

m If you are using more than one Ethernet card, or you are using more than one port on a

multiport Ethernet card, check to see if other computers using the same card or port can

start up. If they can’t, check to be sure the Ethernet port you set up on the server is the

same port the client computer is connected to. It’s easy to mistake Ethernet port 1 for

Ethernet port 4 on a multiport card.

m If the computer has a local hard disk with a System Folder on it, disconnect the Ethernet

cable and try to start up the computer from the local hard disk. Then reconnect the

Ethernet cable and try to start up the computer from the network.

On a NetBoot client, you see the Mac OS desktop but the log-in screen doesn’t

appear.

Make sure Network is selected as the startup disk in the Startup Disk control panel (for

network-startup computers).
