Troubleshooting tips
If you find no workgroup computers in Microsoft Windows Network
(in My Network Places) or if you
miss one or if it is not accessible and you find this error message
"..You might not have permission..", you must check your Windows
Firewall setting. Make sure that "File and Printer Sharing" option
is selected on the Exceptions tab of Windows Firewall configuration
window.

Other possible cause
is Windows is still renewing IP addresses of one or both
network adapters. If this is the case, wait for seconds up to a
few minutes until Windows assigns an IP address to the network
adapter in each PC. If you want to speed up the process, you can try one of these
tips:
- On Network Connections folder, right-click Local Area Connection
and click Repair or select Local Area Connection then click
"Repair this connection" under Network Tasks.
- Click Start, then Run. On the input box, type cmd then
click OK to open Command Prompt. Type ping [the computer name or
IP address of the computer that you wish to query], e.g. ping
PC-01 or ping 192.168.0.1. If you see Reply messages, the connection is up and running.

When configuring Internet connection sharing (ICS) you may find
these message boxes:
- If an Internet connection that requires a
user name and password was saved only for you (i.e. "Me only"
in the Connect dialog box), you would get this message "The user
name and password for this connection were not saved for use by
all users...". Click OK on the message box and in the Connect
dialog box select "Anyone who uses this computer" under "Save this
connection for the following users:".

- After setting up ICS on the ICS host, you might get this message
"...your LAN adapter will be set to use IP address 192.168.0.1..".
This is because the Ethernet adapter on the ICS host is always
assigned a private gateway IP address 192.168.0.1 while before it
was an APIPA address, i.e. 169.254.x.y. If the ICS client hasn't
been changed from 169.254.x.y to 192.168.0.z (where x and
y are any integer
from 0 to 254, and z from 2 to 254), you will lose the network connection. To
renew the IP address of the ICS client by the DHCP server (the
ICS host), repair the
connection from Network Connections folder or ping the computer
name. The last resort is unplug and plug again the crossover
cable. Wait until both network adapters are set with IP addresses
within the same subnet.
