[ILUG] slow network problems

Well, I found a probe utility called vortex-<something> (that's back at work 
now) which tells me full duplex is forced, but I have no way of modifying it. 
I'll have to install a small DOS partition and run the tool from 3com (which 
won't work for me off a boot disk). Something to look forward to on Monday...

Thanks,
Ciaran
