Thanks for taking the time to explain that in detail. Actually, I figured it out before I came back here... what I did was uninstall ICS thru Add/Remove, and removed both NIC adapters as well as the TCP/IP bindings. Then just basically started from fresh that way.
I noticed in the registry, there are 4 almost identical entries. I'm sure they're result of my install/uninstall tries from before... it's using the correct entry now, since the client computer works now... as long as it works, that's all I like
But again, thanks for your help.
