I have a dsl connection with a nokia adsl modem. What I would like to happen is share the internet connection through the win2k server with active directory.

What i know so far is that i should have 2 nic in the win2k server...but that's it.

How do i setup the win2kserver machine so that i manage internet connection from that machine?

    You will have to install two nics.  One will go to the DSL modem and the other to a hub/switch.  You can set the server up as a dhcp server to hand out IP addresses to the rest of the machines.  Then set the clients up to look at the server for their gateway.  So, if the ip address of the server is make that the default gateway of the clients.  

    If you want to use the server as a proxy you will have to set the proxy servers settings in IE on the clients.

    Try this link for more info on ICS:

    Some info on installing ICS:

    On a windows 2000 computer, go to Start, Help, Index, enter: Internet connection sharing, and double-click overview.  The links on that page lead to complete and clear instructions for every phase of the Installation.  With that said, here, roughly, are the general steps:

    To install ICS on the Windows 2000 computer connected to the Internet: Start, Settings, Network and Dial-up Connections, choose the connection to the Internet (or choose  Make a New Connection to run the Network Connection Wizard), Properties, Sharing tab, check Enable Internet Connection Sharing for this connection, check Enable on-demand dialing if applicable and you want the connection dialed whenever needed by the ICS host of clients, Settings, Services, and check appropriate Services, Ok, Ok, and note that Windows 2000 states that the ICS host now has a static IP address of and you need to use dynamic IP addresses on the clients.

    On Windows 2000 client computers click Start, Settings, Network and Dial-up Connections, choose the connection to Start, Settings, Network and Dial-up Connections, choose the connection to the ICS host computer, Properties, Install the TCP/IP protocol if it isn’t already installed.  After it is installed, select it, Properties, Select Obtain IP address and Obtain DNS server address automatically.  After rebooting, Start, Programs, Accessories, Command Prompt, and enter…

    C:\>ipconfig /release

    . to release the IP address.

    C:\>ipconfig /renew

    .to obtain a new IP address from the DHCP server built into ICS on the ICS host.

    Configure Windows 95, 98, 98 SE, and Me clients per  Start, Run, enter winipcfg, select the network adapter going to the ICS host, and release and renew the IP address lease.

    I would suggest that you "not" use ICS for sharing you internet access to the LAN.  The cost of a broadband router is too low...probally only a few dollars more than buying a second nic for your server (some as low as 25 dollars).  The setup will be much simpler and management will be limited only by the type of router that you purchase (most have a wide range of management utilities).

    My past experience with ICS has been problimatic at best.  As a general rule it is not in your best interest to connect a Microsoft machine directly to the Internet...especially a server that might contain important information.
