The 100Mbs adapter is connected to my laptop running Win95 and 10Mbs to WinNT4 workstation. The server network neighborhood shows every computer in the domain.
Workstation shows itself and the server.
Win95 shows the server and the workstation, but not itself. I can ping every ip address with any computer. Otherwise computer will no appear. A whole lot easyer and less problems. Sound like a NIC drivers problem.
