I followed your post to the other thread for changing the MAC address.

Boy, I wish I had more detail from you, cause I'd like to help.

From the very limited information that you provided, I would very cautiously recommend ICS (Internet Connection Sharing) - ONLY if you DON'T have a NAT router/hub that you're using to connect to the ISP. If you have a NAT router like Linksys, etc, then the GUI interface via html will allow you to copy the MAC address of that first machine connected.

ICS is really a last resort, IMHO, cause I've had mixed results. Like: sometimes it works, and sometimes it won't work - I got tired of rebooting the 2 puters until ICS would work. Once it works, then yeah, it's OK.

Alright, if you don't have a router and won't buy one, then setup ICS (your need TWO NICs on the machine connected to the ISP (DSL, Cable, T1??) Remember the NIC that you have connected to the ISP MUST REMAIN the NIC connected to the ISP.
