To force a network adapter to acquire an IP address

Internet Connection Sharing, Internet Connection Firewall, Discovery and Control, and Network Bridge are not available on Windows XP 64-Bit Edition. 

If you are having difficulty connecting the Internet Connection Sharing (ICS) host to the Internet, you can use Repair to obtain refreshed IP address configurations from your Internet service provider (ISP).

If a computer on your network is unable to communicate with other network computers, you can use Repair to force the connection to refresh its IP address configuration from the ICS host.

If the icon for the shared Internet connection does not automatically appear on a client computer (and the Allow other network users to control or disable the shared Internet connection check box has not been disabled), it may be because ICS has not assigned an IP address to your network adapter. An IP address is required in order for a client computer to use ICS Discovery and Control features, connect with to the Internet, or to communicate with other computers on the network.

When ICS is enabled, it automatically provides an IP address for the ICS host's private connection. The ISP assigns an IP address to the shared Internet connection.

Before using the Repair menu command on the ICS host computer, ensure that you have plugged in the adapter that is used for the Internet connection.

Before using the Repair menu command, ensure that the client computer is plugged into the network and that the ICS host is running, configured, and connected to the network.
