Have been running 3 computers on peer network under 98SE under NetBeui -- no problems at all. Changed over to TCP/IP and 2 out of 3 worked fine. The laptop cannot see the network, and the network cannot see the laptop. The laptop can Ping out to others, but others cannot ping to laptop. Reinstalled Windows 98SE. Reinstalled Networking. Changed PCMCIA NIC. Same result. Reinstalled NETBEUI and all is rosy again, but I need TCP/IP and I cannot get it to work on the laptop.
