Printer Code 3/9 in .NET Providing information from your ISP

You can specify a name for your network by opening the Network And Sharing Center and clicking Customize. You then select Public or Private (Private for a SOHO) and type a network name for example, tailspintoys.com. On the next wizard page you click Close to confirm your settings. The Network And Sharing Center now displays your network connected to the Internet, as shown in Figure 7-9. You can get details about the Sharing And Discovery settings and change a setting if you need to by clicking the arrow beside each setting.

Typically, other computers on a wired SOHO will connect to the Internet through the first computer that you configure on the network. To enable this to happen, you need to configure ICS on that computer. You also enable ICS in the configuration where a computer with a Wi-Fi adapter is providing both ICS and wireless connectivity. To enable ICS, follow these steps: 1. Open the Network And Sharing Center and click Manage Network Connections. 2. Right-click the connection you want to share and click Properties. 3. As prompted, either provide administrator credentials or click Continue in the UAC dialog box. 4. Click the Sharing tab, and then select the Allow Other Network Users To Connect Through This Computer s Internet Connection check box.

The Sharing tab is not available if you have only one network connection. You cannot configure ICS unless you have both a connection to the Internet and a connection to other computers on your network.

5. If you want to, you can also select the Allow Other Network Users To Control Or Disable The Shared Internet Connection check box. This is sometimes known as making the connection universal, and it is necessary if you want to determine whether someone else has been making changes to network connection settings. 6. Optionally, you can allow other network users to use services running on your network by clicking Settings and selecting the services you want to allow. When you enable ICS, your LAN connection is configured with a new static IP address (192.168.0.1) and other settings for example, subnet mask, default gateway, and DNS server address. The static address (192.168.0.1) is used as the default gateway for the subnet default gateway addresses need to be static. If you connect other computers to your network before you enable ICS, you might need to change their TCP/IP settings, typically by rebooting. As a general rule it is preferable to add other computers to your network after you have configured ICS. To add a computer to a wired network you need only connect it to the network and turn it on. Provided the computer is set to receive its configuration automatically and the computer s name is not the same as that of another computer already on the network, the computer will join the network and receive its configuration through ICS. If you have changed the default workgroup name (WORKGROUP) on your network, you also need to change this setting on any computer you add. Adding a computer through a wired connection to a hybrid network is the same as adding it to a fully wired network. You simply plug it in and turn it on. By default it should be configured to obtain its IP settings automatically. In this case, however, it obtains them from the WAP (either a third-party WAP or a Wi-Fi enabled computer configured to provide wireless access and ICS).

If your business network supports a VPN connection, you might want to connect to the business network from home by using the VPN connection. You also need to be able to advise users you support on how to do this. For more information, search for Set up a connection to your workplace by using VPN in Windows Help and Support.
