Internet connection sharing ?????

[MIck F]

PLEASE HELP,

I'm connected to ADSL modem from Win 2000 Pro machine and
want to share this internet connection wiht other PCs on
the network.

I can't enable ICS. When I try to do so, I get the
following error message: "A LAN connection is already
configured wiht the IP address required for automatic IP
addressing" I've checked all the other connections and
can't find what's wrong.

I've been stuck on this for days now. What should I do ?

Thanks,

Mick

Mick, the first NIC should be set to DHCP (plugged into
modem). The second nic should be configured to a private
address (10.1...192.168...) enable the ICS on the second
card, M$ uses 192.168.0.1 by default for ICS, so make sure
you're not setting that IP on the second card. If this
still causes problems, go out and spend 50 bucks on a
linksys dsl router so your first machine doesn't suffer!

I've done this and still get the same result. When I try
to enable ICS, I'm told that I can't because "A LAN
connection is already configured wiht the IP address
required for automatic IP addressing"
HELP AGAIN !!!!!!!!!!

Try setting your LAN-side connection to DHCP-assigned
IP before you try to configure ICS, and disconnect the
network cable from the LAN.

If nothing has worked for you, and you really don't have
any visible connections using 192.168.0.1, then
it may be that there is a dud connection that is
fooling ICS in to thinking you have something on that IP.

For example, some network-thing plugged in a
long time ago whose adapter is now long-gone still will
be sitting in the IP connection list waiting forlornly for
the return of its adapter. ICS should ignore these, but I
don't know if it does.

IF ALL ELSE FAILS, you can review and delete the
non-existent connections by editing the registry. The information
for these connections are in the {...} subkeys at the beginning
of HKLM \ System \ CurrentControlSet \ Services. You have to
inspect the data in each one (in Parameters\tcpip) and then rename
or delete the {...} subkeys out of the way for the connections that no
longer exist. Don't get rid of any current connections of course.

This is somewhat serious monkeying around, and I don't advise it
unless all else has failed. If you dig a really deep hole, an F8-boot in
to last-known-good will restore the old services key, or if you rename
connections out of the way (my recommendation), just rename
them back.

The previous poster was right -- for ~$50 you can
get a NAT router that will give you freedom from ICS as
well as much better security, and it is a wise investment.
