I'm planning on multihoming my server client network at home.

my 100 card is 192.168.111 and my 1000 card is 192.168.111.

I can get the machine to ping both address but can not contact any ip
address with in the ip scopes.

i have setup the cards so the 100 (the network connected to my internet) as
having the defualt gateway (my ADSL Router). I also manually set the metric
for each card with the 100 having the higher rating. I am assuming i should
do that

But it still doesn't seem to work.

I've checked the routes but haven't configured any manual routes and i also
enable IP Routing on the machine.

I am not running routing and remote access on my 2003 yet. I don't think
should have to as basically it all internet direct packets go through the 100
card and all my domain based packets go through the gigabit card.
 
I can get the 222 network to communicate but not the 111 network. Below is
the route table of the multihomed machine.

You show 192.168.111 for both cards. Is that right? It isn't
possible to use two different cards in the same subnet. The system
will use one or the other, but not both of them.

Use a different subnet for each card (for example 192.168.111 and
192.168.222, both with subnet mask 255.255.255.0). The system will
automatically use the 100 card for Internet access because it has the
default gateway. The system will automatically use the 1000 card for
access to IP addresses in its subnet. You shouldn't have to specify
any manual routes or metrics.

If that doesn't help, please reply to this message in the news group
(not by E-mail) with a copy of the computer's route table.

The route table looks fine to me. I have just one question:

The subnet mask for each network card is 255.255.255.248. That means
that each subnet has a maximum of 6 hosts, with these IP addresses,
and that no other LAN IP addresses are accessible:

192.168.111.1 - 192.168.111.6
192.168.222.1 - 192.168.222.6

Is that how you've set up the IP addresses?

Make sure that a firewall isn't blocking access. It can be tricky
configuring a firewall to allow access on two LANs with different
subnets.

Yes that is correct, the IP ranges I want to use are

192.168.111.1 - 192.168.111.6
192.168.222.1 - 192.168.222.6

i shut the machines down last night (My time) and today i started up the
machines
had to reboot the ADSL router (Don't know if this had any effects) but it
all works now on both
subnets.

Thank you anyway at least i know that what i was doing was right. I found
that there was very limited information
