Problems with networks and file sharing
Solutions to common problems
If you are having problems using the network or file sharing, try the following
before attempting further solutions:
m Make sure that AppleTalk is turned on in the Chooser.
m Open the AppleTalk or TCP/IP control panel and make sure the correct
network type is selected.
m Make sure that all the network software is installed. The Network and
AppleShare extensions should be in the Extensions folder. If you want to
use file sharing, the Sharing Setup control panel should be in the Control
Panels folder, and the File Sharing extension should be in the Extensions
folder. If any of these items is missing, use the CD-ROM disc that came
with your computer to reinstall the parts of the system software you need.
m Make sure the network is working by opening the Chooser and checking
for the shared disks and printers you usually use.
m Try connecting to the network from a different location, or connecting a
printer or another computer directly to the PowerBook using network
cables. If that works, the problem is likely to be in the network. If it doesn’t
work, the problem may be in the PowerBook or its network software.
