I am having trouble installing my PC Card network card on my laptop under NT4, so am having to use Win2000 (which as you can imagine is a bit sluggish on 32MB RAM). I'm planning a RAM upgrade, but if I could get the thing networking under NT4 for now it would be great. I install Windows NT 4 (SP1 already on install CD) then install my network card and drivers. The drivers install, and I am prompted to insrt my NT Workstation CD. This installs all the right services, and I reboot. However, whatever settings I try, WinNT happily says everything is OK, and the card's 100M led lights, but no data can be sent to or from the laptop. The Workgroup setting is identical for both machines, and I have tried TCP/IP and NetBEUI. I have also installed SP6a after installing the drivers and services, but to no avail. The laptop needs to communicate peer-to-peer with a WinXP; and Server 2003 for terminal services; and possible Linux. The other machine (there's only one machine that the lappy needs to network with) seems to be configured OK. Could there be a configuration problem on my part, or is the network card driver written badly, or is it something else?
