hi, i hope to build a home network, but it doesn't work. I have two desktops,each installed win2000 with sp4. In desktop1, two net card are installed. one connected to ADSL, the other connects to the second desktop. there is only one net card installed in the second PC. an interesting thing is that when i connect these two PCs, i found the link LED lights, but i can't access the other computer. i checks its property, it shows that there are packets sent, but with 0 packets received. the same property happed to the second computer. I am sure the twisted line connecting these PCs is ok and all PCs has been set to correct IP address, such as 192.168.1.10/sub 255.255.255.0 or 192.168.1.11/sub 255.255.255.0. well, i then build up a wireless network without AP, i.e. Ad hoc. the indicator shows that the network is ok, but i found it is still only sent packets but without any packet received. Can anybody help me to find the answer? how can i build my home net? thanks very much. regards skyworld
