    Internet Connection Sharing (ICS) is a Windows service that allows a computer connected to the Internet to inventory its Internet connection to other servers in a local group (LAN). ICS provides Dynamic Host Configuration Protocol (DHCP) and Network Address Language Translation (NAT) services for computers on a local area network.

    This article describes how to set up Internet Connection Sharing on a computer that is running Microsoft Windows Server 2003.


    ICS enables you to use Windows Server 2003 to connect your optimized work or home network to the Internet. ICS provides network address translation (NAT), IP addressing, and vendor resolution services for all computer equipment on a small network.

    • Digital Authorization Line (DSL) or Cable Modem connected to an Internet Service Provider (ISP) and an activated DSL or TV account.
    • Two network adapters are installed. This article explains how to install an optional NIC.
    • Network already configured for TCP / IP.

    Before continuing with the maintenance in this article, please note the application specifics:

    • Do not use ICS on a network that я:

      • Use static IP addresses

      • Has a real Windows Server 2003 domain controller

      • Use additional DNS servers, gateways or DHCP servers

        Because ICS creates static IP focus for your network adapter and assigns IP addresses to other computers on your network, you will lose your new connection to the rest of the particular network if other computers on the network are already providing these services. If more than one of these conditions may exist on your network, you should take advantage of Windows Server 2003 NAT instead of ICS. For more information on NAT, see the Windows Server 2003 Help


    • Do not frequently create a virtual private network (VPN) port to connect to the corporate network from the ICS computer. In this case, by default, all traffic from the ICS computer, including traffic from clients on the local network, is forwarded to the corporate and corporate networks through the VPN connection. This means that ISPs are no longer available and all client computers will eventually send data over a logical connection created with credentials And the main user of the ICS computer.

    • Do not configure ICS on a computer that is a suitable VPN server. If your Windows Server 2003 computer acts as a VPN for your server, you should take full advantage of Windows Server 2003 NAT.

    Install The Hourly Ethernet NIC On The Host Computer

    How do I connect to Internet on Windows Server 2003?

    Click Start, click Control Panel, and then double-click Network Connections.Right click Local Connectionnetwork, and then click Properties.Click the General tab and make sure Client for Microsoft Networks and Internet Protocol (TCP / IP) is displayed and selected.

    To install a different Ethernet adapter for the host computer, you must be logged on as a member of the Administrators group.

    1. Exit the program correctly and then physically add the entire adapter network.
    2. Restart your computer.
    3. If a Newly Found Hardware dialog box is available that lists the names of the installed network adapters, click Next.
    4. On the Install Device Driver page, click Enabled.
    5. On the Find Driver Files page, click the media package that contains the drivers, usually the network card that you usually install. For example, click CD Drive, Floppy Drive, or Hard Drive Directory.
    6. On the web pageto find the driver file, click Finish.

    Configure ICS Host

    The ICS host connects to a second NIC on all existing TCP / IP networks. At logon whenever a member of the Administrators group configures the host’s ICS computer.

    ICS And Networks

    How do I enable Internet Connection Sharing?

    Click Start, Settings, Control Panel, Network, and also Dial-up, [Dial-up ].Click Properties.Select this Sharing tab.Select “Enable Internet Tethering for this connection.”

    You can use a dial-up network with Internet access. It is interesting to note that the network usually has a connection with less data usage. This connection is incomparable to multiple connections, useful when computers usually share a connection. In addition, the dial-up network is not permanent (you must dial manually to connect). There may also be initial delays in connecting to hosts on the Internet.


    Please note the following to avoid ICS configuration issues:

    • Do not connect the hub directly to a DSL or cable modem. If you do this, your internal network will be vulnerable to other computers created on the Internet. If you connect your computer directly to a reliable cable or DSL modem, you should turn off File and Printer Sharing to restrict Internet access. However, in the e In this case, your network may avoid sharing files and printers, which can be the main reason for creating a network.

    • Make sure to uninstall any third-party firewall software or Internet Express. Make sure that only a specific ICS-compliant computer provides IP, transfers DNS names, or acts as a default gateway. Otherwise, ICS may not work or you may experience unexpected behavior.

    • You cannot change the ICS configuration. For example, no one can prevent ICS from assigning IP addresses or change IP chats assigned by ICS. If you need this functionality, you should use NAT.

    • The ICS computer automatically assigns names to IP addresses, transmits DNS names so you can use the Internet to resolve names, and then designates itself as a standard terminal for Internet connections. If an ICS-enabled computer is not available, other client computers on your website will not be able to access the Internet.

    • If you change your TCP / IP network usage, remove the protocol instances And NetBEUI as soon as you find them. NetBEUI is idle and may slow down this network.
