I have two computers: a desktop (Windows 7 Professional) with an ethernet jack in the motherboard and room for another (PCI or USB) and a laptop (Win7 Home Premium) with an ethernet jack. Internet connectivity is available through an ethernet wall jack (no access to switch/router). If I were to purchase a second NIC for the desktop (and have ample ethernet cables), would a setup meeting the following criteria be possible? If so, how?
- Desktop has connection to internet through wall
- File sharing is possible (both ways) between the two computers (default Windows network sharing and drive mapping)
- The laptop is not connected to the LAN coming from the wall (from the network administrator's POV - only one of the two devices can be connected at any time)
- Not necessary, but nice: a way to choose which folders are shared to which network. On the desktop, which would be connected to both the internet/building LAN and the laptop, there are some folders which I would rather only be available to the laptop.
Any help would be greatly appreciated.
