ICS question!

I have a desktop with one NIC and I have a Laptop with a NIC.
My Desktop is connected to the internet.
Question: Do I have to add another NIC to my Desktop to setup ICS so my Laptop can surf?

Don't tell co-workers your going for a Cert that they don't have. They may think your trying to take their job.

If you have dial up then no. All you will need to do is hook up a cross-over cable to the desktop and laptop.
If you have cable or DSL then yes, since this connection is already taking your only NIC you will have to put in another one on your desktop.
I am guessing you are aready using the one Desktop NIC for your internet or you wouldn't be asking this. Your setup should be something like this:
Desktop
NIC 1 - WAN
NIC 2 - LAN
Laptop
NIC - LAN - connected to NIC 2 on the Desktop Via crossover.
You can use either USB or IEEE1394a/b Connections to connect machines for ICS however you are limited in the length of cable you can use. This defeats the object of it because why use your laptop when your already practically sitting at your destop. If i were to use this method it would only be for file transferring between machines.
While inserting a second NIC would restrict you to a network of 2 computers only.
Hmm this won't work.
You require a router to route the packets between the different networks this is what ICS does, its a form of NAT. NAT (network address translation) is used by routers.
