I'm pretty sure it was one computer that was causing the problem.   One of 
the symptoms was slow network traffic between other machines -- down to 
50kbps sometimes on 100Mbps segments.  Just powering up the offending 
computer and letting it sit at a bios screen would cause the problem. 
Power it down again and everything else went back to normal.  It was a 
cheapie MB and power supply, and I never tried anything else after the 
ferrite core fixed it.
