I am running Windows xp service pack 2. I recently got a broad band connection via Wimax,I want to share this connection with 3 computers on my LAN I have already installed the extra NIC and configured it to(IP gateway:blank dns:Same as the one given by my ISP).The computer indicates this connection is fine.
The problem starts when I try to enable Internet connection sharing on the NIC connected to the WIMAX IDU,I am notified that when connection is shared my Lan adapter will be set to 192.168.0.1. On clicking YES it then goes "An error occured when ICS was being enabled (null)"
Where am I going wrong?
pS I can use Internet the single machine with no problems

Brief troubleshooting notes for : this is a common Windows XP-era ICS problem with a few predictable causes — required Windows services not running, a third‑party firewall or corrupted firewall/ICS registration, duplicate/private‑subnet conflicts, or Winsock/TCP‑IP corruption. Start with a short checklist rather than diving into registry edits. (support.microsoft.com)

Quick checklist (do these in order):

  • Open Services (services.msc) and make sure the ICS/SharedAccess dependencies are running (RPC, Remote Access Connection Manager, Remote Access Auto Connection Manager, Telephony, Network Connections, Network Location Awareness, Plug and Play, Application Layer Gateway). Restart the machine after changes. (support.microsoft.com)
  • If a third‑party firewall/AV is installed, temporarily disable it and make sure the Windows Firewall/SharedAccess service can start — ICS often fails when the firewall service is missing or disabled. (learn.microsoft.com)

Repair network stack and drivers:

  • Run these from an elevated command prompt and then reboot:
    netsh winsock reset
netsh int ip reset resetlog.txt
  • Reinstall or update NIC drivers and disable any extra virtual adapters (wireless utilities, VPN clients, virtual Wi‑Fi adapters) before retrying ICS. Winsock/TCP‑IP resets are Microsoft‑documented troubleshooting steps. ()

If ICS still refuses to enable, check for address conflicts: ICS will pick and assign a private subnet on the LAN side; if that subnet is already used by your router/AP or another adapter the share will fail. Change the router LAN range or follow Microsoft guidance to change ICS’s default scope (registry method only if comfortable and after backing up). If this sounds like too much hassle, a small NAT router/switch (what recommended) is the simpler, more reliable fix for sharing a single broadband link. (helparchive.huntertur.net)

I assume your setting up a star network with cross over cable.

Why bother get a router and a hub or switch if need be.
