Ok, I'm aware this might not be the best forum to post this question in, but I figure I'll be able to reach more people here and hopefully get an answer quicker Right to start off (and hopefully keeping a long story short), I have a powerbook running osx 10.3 and I was running a Windows 2K machine. The net was initially going into one ethernet card on my windows machine. And then the powerbook was connected via another network card in the windows machine. ICS was enabled on the network card that was connected to the modem and everything that need to be enabled on the mac end was, and I was online with my powerbook. Now I have a new PC with Windows XP Pro. I'm using exactly the same set up with ICS enabled on the network card connected to the modem and my Powerbook connected to the other network card. Now if I turn off my mac on windows it says, network cable unplugged, so they definately see each other (and theoritically, miss each other, excuse the pun), but my mac can't get online. Now seeing as I primarily use the PB and my family use the Windows machine this has left me at a loss. I'm aware routers are very cheap nowadays and will probably solve all my problems, but at the present time I simply do not need one when ICS solves all my problems, well used to. Does anybody have any thoughts? All feedback is very much appreciated.
