Help with Internet connection sharing Vista.

[Katoom]

I have a HTPC and my PC plugged into a router to the internet, this works fine.
I'm trying to connect the HTPC directly to my PC to use the 1Gb lan(it has 2), but still be able to share the internet.
I can plug the HTPC directly into my PC, and share files ok, but it can't see the net. I have set my internet lan to Share it's connection but it still doesn't work.
So this is what i have. Internet to PC ok, PC to HTPC ok, HTPC to internet No.

Could someone help please?

You don't need ICS, just bridge the two interfaces on the PC.

Sir, your a star.

I've been faffing about for ages, i'm sure i tried that but it wouldn't let me(something else i'd done).
It's all working great now.
Thanks.
