My existing network used to work, but now it doesn’t.
O
Check the existing network installation to verify that all cables
are still attached and all link/activity lights on the other network
devices read correctly.
O
Verify that the network settings on all of the computers are
correct.
My newly networked computer sees my network but can’t find
the Internet.
O
Check the Internet settings on another computer in the network.
If your computer can’t access the Internet, it might be looking
for the wrong IP address or trying to use the wrong Internet
protocol. Although the IP address might have been correct on
this computer previously, if you changed Internet service
providers (ISP) or reconfigured your network, then all of the IP
addresses in your network could have changed as well. See the
documentation that you received from your ISP for the correct
IP addresses and protocols.
O
Make sure the computer has been correctly configured to work
with your ISP’s connection settings. Compare the settings of a
computer on the existing network with those of the new
computer being added. Verify that both computers are
attempting to connect to the Internet in the same way. For
example, if your ISP uses a Dynamic IP (DHCP) connection,
make sure all computers on your network are set to DHCP in the
Network section of the Windows Control Panel. For more
information, search for Network or DHCP in Windows Help.
File and Printer Sharing Problems
This section will help you solve common problems with sharing files
and printers on your network.
To learn how to add or share files and printers over your network,
see Windows Help.
I cannot access shared files over my network.
If you want to share files between computers on your network, all
computers must belong to the same workgroup. Check the
workgroup names on each computer by using the following
instructions.
Windows XP:
1. Click Start, and then click Control Panel.
2. Double-click System, and then click the Computer Name tab.
