Do you use the Media Center machine to watch or record TV? If so, it
needs Internet access to update its program guide.
I'm assuming that you have a broadband router that provides Internet
access to your network.
1. Assign a static IP address and subnet mask to each no-Internet
machine. The IP address should be in the same subnet as the other
computers, but outside the range of addresses assigned by the router's
DHCP server. Don't assign a default gateway or DNS server address
to those machines.
2. Configure the Internet machines to obtain an IP address
automatically. The router's DHCP server will configure them.
3. Your router acts as a firewall, preventing unauthorized access to
you computers from the Internet. Each computer should also have a
firewall program as a second level of protection. Configure the
firewall to allow access by other computers on the local area network.
The Windows Firewall that comes with XP and Vista is fine.
