Lost part of my LAN

Here's a strange problem, at least it is to me. I have
cable internet, which runs into computer #1 via ethernet.
I have a second NIC card in computer #1 which goes to my
hub, and from the hub to computer's #2, #3, and #4.
They've been working great for many months now. All are
running XP Home Edition with all of the MS updates.

I rebooted computer #1 the other day, and now, all 4
computers can talk to each other (I can explore all
harddrives from any of the computers, and use any of the
printers from each computer), but only computer #1 has
internet access. I've pulled the NIC's out, and
reinstalled their drivers, but still don't have internet
on any of them except for #1. I've went in and enabled
ICS, still nothing. I even tried bridging the NIC's, but
ICS already has done that.

My broadband NIC is set to obtain the IP address
automatically, which works great. The LAN NIC is manually
set to 192.168.0.1, and the other computers are all set to
192.168.0.xx. Subnet masks are all 255.255.255.0. On the
LAN side, there is no DNS server address set, and no
default gateway's set.

What am I missing here? Thanks for any suggestions! If
possible, could you email the suggestions directly to me
at (e-mail address removed). I really appreciate it!

You might try running the network setup wizard on #1 again

Wes,

Asked here, answered here. For everybody's benefit.

When you enable ICS on the server, and DHCP on the clients, the following
happen:
1) The LAN connection on the ICS server is set to 192.168.0.1.
2) The LAN clients automatically get ip addresses from the ICS DHCP server.
3) The LAN clients automatically get default gateway set to 192.168.0.1.

Please provide ipconfig information for the ICS host, and for at least 1 client.
Start - Run - "ipconfig /all >c:\ipconfig.txt" - Open c:\ipconfig.txt in
Notepad, copy and paste into your next post.

Did you enable DHCP on the clients?

You have broadband. Any particular reason why you haven't put a router in place
to protect your LAN, and to share the internet service?

With broadband, you'll be better off getting a router to share the internet
service. $30 - $50 gets you a router, you'll need just one Ethernet card in
each computer, you can disconnect either without affecting the other.

All computers will be safer. The router will block any malevolent internet
traffic. This further protects the internet, from your becoming infected and
spreading the infection.

All computers will run better, with the router blocking the trash infection
traffic.

All computers will run independent of each other. Right now, if you have
internet connectivity on multiple computers, either you are paying your ISP for
multiple connections (a waste of $$$), or you have to have one computer on
whenever you wish to access the internet from any other. With a router, neither
is true.

If you can afford to have more then one computer, and broadband, you can afford
a router. For many reasons.

And please don't contribute to the spread of email address mining viruses.
Learn to munge your email address properly, to keep yourself a bit safer when
posting to open forums. Protect yourself and the rest of the internet - never
post your address unmunged.
