Well on my currernt network, we have a Cisco 100MB switch, and 3com 3c905C
cards in the PCs, the PCs take about a minute after card initialisation to
actually find the network, which under NT means you can't logon for a
minute, and Linux blocks before mounting the NFS drives....
I've tried Donald Becker and 3com drivers, and fecked with numerous
settings, I suspect the switch as my Xircom 100MB also takes a bit of
time to init....
Most bloody annoying...
