Subnet:
DNS: Acer Host: LINKSYS

Home network configuration.

Practical, low-risk approach for ' topology: treat the domain controller as the internal DNS/DHCP/AD server and put a NAT device (either the server acting as NAT or, preferably, a small hardware router) between the cable side and the 10.0.0.0/24 LAN. Internet Connection Sharing (the Microsoft KB referenced by ) will work for tiny, non‑domain setups, but running ICS on a domain controller is fragile and can introduce DNS/DHCP conflicts. Prefer RRAS (Windows Server) or a dedicated router.

Recommended configuration (concise):

  • Identify NICs: “External” = link to the Linksys/cable gateway; “Internal” = link to the SYSLINK switch and clients.
  • Assign static addresses:
    External NIC: 192.168.0.2/24, Gateway: 192.168.0.1
Internal NIC: 10.0.0.1/24, no default gateway
Clients: 10.0.0.2–.3/24, Gateway: 10.0.0.1, DNS: 10.0.0.1
  • Server DNS/DHCP: make the DC’s primary DNS point to itself (10.0.0.1). Configure DNS forwarders on the DC to the ISP or a public resolver so external names resolve. If DHCP is used, set scope options to hand out 10.0.0.1 as gateway and DNS.

Services and software:

  • On Windows Server, enable RRAS and configure NAT on the External interface and mark the Internal interface as private. RRAS preserves AD/DNS behavior and is preferable to ICS for domain controllers.
  • If RRAS is unavailable and a router is not an option, ICS can be used as a last resort—expect the internal NIC to be reconfigured and watch for conflicts.

Quick checks and troubleshooting:

  • From the server: ipconfig /all, ping 8.8.8.8, and nslookup microsoft.com to confirm routing then name resolution.
  • From a client: ping the internal gateway (10.0.0.1), then 8.8.8.8, then a hostname. Common faults: wrong gateway on NIC, duplicate IPs, DNS on clients pointing to ISP (breaking AD name resolution).
    Security note: avoid exposing the DC directly to the internet. A hardware firewall/router between the cable modem and the DC is the safest, simplest long‑term fix.

The post by about bad sectors is unrelated to this thread.

I responded to this question on the 11th. It seemed from your first post that you did not want your home pcs to be able to access your other workgroup computers. Please don't repost the same question without responding to suggestions already given. If all you want is instructions on how to configure Internet Connection Sharing here is the whole thing from Microsoft.
