Excessive Ethenet Collisions: v.091/2.0.36/21143

The network folks here have taken me off the hub, since the number of collisions
coming out of my workstation is considered exessive...something like 40% of
capacity (whatever that means). Anyway, the only tulip option that works is
the default, nothing else will connect with the network. The hub is a 10Mbs
half-duplex Cabletron.
This is coming from another 2.0.36 workstation, which is running just under 20% collisions
according to the network guy's stats. I've included what I hope is some useful info
below, though not being a network type I'm not sure what's really helpful. I've tried
(on the other system) eliminating any program that might send packets to the network,
a list of running processes is included in case anyone might see an obvious culprit
there.
Any suggestions would be appreciated.
