My host is connected to my Corporate Network. If I enable ICS on the primary adapter, wont I then potentially be issuing IP address to other corporate machines (not desired)?
You announce a good point - something I had forgotten to place in my post (and the corrosponding document).
As we know, ICS will start a DHCP server on the host machine - often the problem here, is that most people run their local networks (I guess this even applies to some corp nets) on the 192.168.0.* subnet. Unfortunately, the DHCP server will use the same subnet/ip range.
When using this solution on a LAN which is on the 192.168.0.* subnet, there's no way around it. You will need to change your network to use, for instance, the 192.168.2.* range instead - this way, there will be no conflicts.
So I think your question is confused by the fact that the host becomes a DHCP server, and it may then try issue IPs to other people on the network - and yes, the answer is it will if your network is on that particular range. If people on your network are closer to your machine on the network nodegraph - your host will try to respond to their dhcp request if they are not specifying a dhcp server directly (I think).
I had to change my home network to use the 192.168.2.* subnet by altering my routers configuration settings - if you check out your routers docs, it should show you how its done - and if you're like me, you'll just go directly into the configuration manager for your router and find 192.168.0.* and change it over.
I haven't tried working out if there's a way of changing which subnet the ICS DHCP server uses - let me know if you can find this out :)
I'll do some more research into other ways of utilising my corp Internet connection. If I was to let an unauthorised DHCP server loose on the wire, I'd be choked to death with that exact same wire :)

Top work Matty. I know that I'll need this one day. Added to my del.icio.us list.

Please note that I have updated the post to incorporate this information.
