Help! Ics With Raspppoe

[skyworld]

Hi friends,

i build my homenet with two computers. One is win2k with sp4, the other is win XP. i use ADSL to assess internet through computer with win2k by RASPPPOE. which i call pc1. i have installed two NIC in pc1. now i hope to access internet both from pc1 and pc2. I think i have enabled ICS from pc1 with sharing internet item, but i can't access internet from pc2. and a strange thing is that if i connect pc2 to pc1 then i can't access internet, but if i disable the NIC which connects to pc2, then i can access internet. I have sweeped both pcs to check if there is any virus. but there is none. So can any body help me to solve this problem? thanks.
