I would like to know what can cause excessive collisions on Ethernet.  I 
realize that collisions are a fact of life on ethernet.
My net analyzer shows a large number of local collisions (as high as 20%).
I can't isolate to just one or two machines.  I also don't have any one
machine which is completely non functional.  In other words I haven't
nailed it down to a problem with one machine (bad card or ?).  What other
things should I look for?  Ground problems?  My cable scanner doesn't show
any bad segments of cable.
MOst of the machines are on Thinnet.  There is fiber between buildings.
Total of about 150 stations campus wide.

Any Ideas?
Thanks in advance.
