I have recently purchased the D-Link 10/100 Network in a Box. I have only two computers I am trying to network together. I cannot find the other computer on EITHER of the computers (they are not showing up in my Network Neighborhood. They are both connected to the same workgroup. I try to 'find' the computer, and only the computer I am on is located. How do I make them appear? All the hardware is installed correctly!!!!
