Hi again Bino
It should be "Logon to MS Networks" on both as you've created a peer-peer MS network.
You are right that it wants to use auto-addressing, I've had better results myself just setting up the initial LAN with my addresses and then running ICS on top of that. Luckily these days I just use a Linux box linked to the DSL and everything's hunky-dory!
The ICS site that MAC has shown above is great......
Best of luck
