SYMPTOMS
Consider the following scenario. You have a computer on a network that has Internet Connection Sharing enabled. Then, you install Microsoft Windows Live OneCare on this computer. However, computers that were previously able to share an Internet connection through that Internet Connection Sharing-enabled computer can no longer access the shared connection.



CAUSE
Internet Connection Sharing uses one or more network ports to share an Internet connection with other computers on the network. By default, these ports are disabled by the Windows Live OneCare firewall. To enable a shared connection, you must enable a port through the Windows Live OneCare firewall by using the Firewall connection tool.



RESOLUTION
To resolve this issue, use the firewall connection tool to allow the Internet Connection Sharing ports to be accessible by other computers on your network. To do this, follow these steps:
 * 1) Start Windows Live OneCare.
 * 2) In the left pane, click View or change settings.
 * 3) Click the Firewall tab, and then click the Firewall Connection Tool..
 * 4) Click to select the Internet Connection Sharing – use one internet connection for several computers check box.
 * 5) Click OK and close the View or Change Settings options.
 * 6) Restart the computer and test the shared internet connections on the other computers.
