Windows Vista How can I share an internet connection with 2 Windows 7 computers?

[Gil80]

I have a dual LAN on my mother board. I've enabled the ICS in the sharing tab in the IPv4 Properties.
1=Host
2=Guest
No.1 is my main computer and has 2 LAN cards on the motherboard.
No.2 is the Media Center.
I have a LAN cable to connect them. It used to work when No.2 had WIN XP.

Now I can see them in the network area but No.2 can't access computer 1 and can't use internet from no.1

How to fix this?

you need to make a bridge connection on the PC with 2 LANS so that they see each other
