* 3 PCs in peer to peer. W2K PC was using ICS & dial-up to reach Internet.
* Upgraded to broadband with router to share the connection.
* Disabled above ICS, changed ethernet card from fixed IP to use DHCP from
router.
* All 3 PCs sucessfully getting IP via router's DHCP function.
* Other 2 PCs can sucessfully see both LAN and reach Internet via broadband
* The W2K PC can only reach devices on the LAN, including the router's
web-based setup, but cannot reach anything outside the LAN.
It seems like the W2K PC is blocking any IP address outside the LAN, perhaps
still trying to route them to the modem (which is idle)? Is the routing
component of ICS still active, in spite of being turned off?
Suggestions on how to fix this issue?

I have a similar setup, but am able to use a DSL connection with no
permanent IP (ISP's DHCP). On my W2K computer with ICS I have three
cards seen in Network and Dial-up Connections dialog. Two physical
lan cards, and one "virtual" lan card which is really a "redirector".
One of the physical cards goes to my internal lan, and the other
physical card is attached to the DSL modem, basically just acting as
a passthrough for frames/packets to the modem. The virtual card is
recognized by windows as a physical card eventhough it is just
software, passing packets that are meant for networks beyond
192.168.x.x out.
In my case, I HAVE to set my ISP's DNS server addresses in the
properties of the physical card for my internal LAN. Therefore, the
card acts as a gateway (192.168.0.1) for internal computers, which in
turn knows exactly where to resolve any address not available by wins
or netbios (it pushes the name resolution request out to ISP DNS
servers because I put the addresses into the card's properties
dialog).
In your case, try putting your ISP's DNS addresses directly into the
W2K's card properties. This is kind of a fenagle, but see if it
works.
Or, as anyone else would tell you, totally remove all the network
adapters from the Dialog, redetect, and see if that works... of course
it probably won't, but...
If you can't see a DNS address when you do an ipconfig /all then DHCP
isn't serving one...
And one last thing. I have problem on my net right now. Opposite of
yours (two of my computers on the internal lan cannot ping each
other), which led me to find out that only 16bit ISA NE2000
compatible cards can talk to my ICS computer on the internal net. Any
pci card in any computer with any operating system on my internal net
cannot ping the pci card in my ICS computer! I'm totally at a loss.
I've switched out pci cards; they're good cards, etc... So, you might
try, if you can, changing the card in that W2K computer to an older
generic ISA card and see what happens... I currently have an NE2000
compat. on order right now just get everything talking together.
Mystery. I can put a Linksys 16 bit ISA card into the computer and it
pings and connects...??!!??
