Win 2k NIC – “no packets received”

I picked up 4 IBM refurb workstations with Win 2K Pro on them. Added them to the LAN (NT4 server) all worked fine. Now 2 of them are showing no packets received (win tool tip)while if I run IBMSET software, IBMSET shows packets being received. Stillthe network is nowhere to be found. I’ve looked at this so closely that I’m probably overlooking something simple. Please enlighten me if you will.
thanks.
