Short summary and a clear plan: the LAN is talking to itself but client machines are not getting out to the Internet. Decide which device will perform NAT/DHCP for the network — either the hardware router or the Windows XP machine — and make that the single gateway. Mixing both, overlapping IP ranges, or leaving a firewall enabled on the gateway machine are the most common reasons for the behavior described by . and touched on the same themes; ’s question about which PCs can reach the Internet is exactly the right troubleshooting angle.

Quick diagnostic checklist (run from a client, then from the gateway machine):

  • Run ipconfig /all and confirm the client has a default gateway and DNS servers set.
  • ping the LAN address of the machine/router that should be the gateway (tests local reachability).
  • ping 8.8.8.8 (or another public IP) to test basic IP routing to the Internet.
  • nslookup www.example.com to test DNS resolution separately from routing.
  • tracert 8.8.8.8 to see where packets stop if routing fails.
  • On the gateway PC check routing with route print and temporarily disable any host firewall.

Common fixes, depending on which approach is chosen:

  • If the hardware router will provide Internet: disable ICS on the XP host, connect the switch to the router LAN, and let the router run DHCP/NAT. Ensure clients use the router as their default gateway.
  • If the XP host will share the Internet: enable Internet Connection Sharing only on the Internet-facing adapter. ICS will supply NAT and a DHCP range; clients must use the ICS host as their gateway. Do not run the router’s DHCP at the same time on the same subnet.
  • Avoid bridging the two NICs on the gateway, avoid overlapping subnets, and check third‑party firewalls.

Useful to record while troubleshooting: ipconfig /all, route print, and the output of tracert/ping to a public IP. These show whether the problem is DNS, routing/NAT, or a blocked/filtered connection.

that diagram does not make sense at all,

make sure you don't have any weird proxy settings on your web browser.

also, has this happened before? can you ask your question more clearly?

that link has the tutorial for sharing internet from a computer, not using a router.

will none of the PC's connect to the Internet?

will just 1 of the PC's Connect to the internet?
