Internet Gateway Device Discovery and Control (IGDDC) is a Windows feature designed to help you manage Internet gateway devices (devices that connect a home network to the Internet), such as routers or base stations. With an Internet gateway device, you can share a Digital Subscriber Line (DSL) or cable modem Internet connection with all of the computers on your network.
If your home network has an Internet connection through an Internet gateway device or a host computer (one that connects directly to the Internet), you can use IGDDC to monitor and change settings for the Internet connection from any computer on the network that is running Windows.
IGDDC helps you manage and control a wired or wireless router or a computer configured for Internet Connection Sharing (ICS).
With IGDDC, anyone on the network can:
Remotely connect or disconnect the shared Internet connection.
Open or close ports through the firewall.
If your network has a host computer, the network administrator can control these settings and prevent other network users from accessing them.
If your router or base station doesn't work with UPnP technology, IGDDC won't work.
Open Network Connections by clicking the Start button , clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage network connections.
Right-click the connection that you want to share, and then click Properties.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the Sharing tab, and then select the Allow other network users to connect through this computer’s Internet connection check box.
If desired, you can also select the Allow other network users to control or disable the shared Internet connection check box.
Optionally, to allow other network users to use services running on your network, click Settings, and then select the services you want to allow.
Open Network and Sharing Center by clicking the Start button , clicking Control Panel, clicking Network and Internet, and then clicking Network and Sharing Center.
If you enable ICS and then turn on network discovery in Network and Sharing Center, an Internet gateway device icon is added to the Network folder on the Start menu. For more information, see What is network discovery?
If you don't see the icon on your computer, make sure that:
Your computer is connected to the network.
Your Internet gateway device or host computer is configured correctly and is connected to the network.
If the icon still does not appear:
Right-click the connection, and then click Diagnose. Windows will try to diagnose or repair the network connection.
On computers running Windows XP, the Internet gateway device icon appears in the Network Connections folder, under Internet Gateway. On computers running Windows 98 and Windows Millennium Edition, the icon appears in the Communications program group and in the taskbar.
To use IGDDC on computers running Windows 98, Windows 98 Second Edition, or Windows Millennium Edition, run the Network Setup Wizard from the Windows CD or floppy disk.
