Well, basically if you are trying to use the PC as a NAT (network address translation) server all that needs to happen is for the mac to be setup for the same ip address range as the internal (not internet accesable) ip range as the PC. Whatever software you have on the PC should assign two IP addresses, one for internet access and one for the internal network. Set the IP address on the mac to the same range as the internal address on the PC and set the PC's IP as the router or gateway under MacTCP, also make sure that the subnet masks match. I have not used MacTCP in ages (that software is a good five or six years old) but it should work. Life will be a little easier if you install open transport, but either should work. Yes, either way it is going to disable her current internet access. If you just want file sharing between the two then use Dave on the mac or Miramar's PC MacLAN on the PC. Neither of these require IP accesses to be configured. -Mike
