When you say "both ends" do you mean computer and network switch?  Or
do you mean computer A and computer B?  Is the switch managed or
unmanaged?  You can't set full duplex on an unmanaged switch, it is
always in auto.  If you have an unmanaged switch you MUST set the
computers to auto or to half.  Setting them to full will most
definitely cause problems.  The auto-negotiation specification says
a port set to auto must choose half if the other end is not set to
auto.  This is an extremely common misunderstanding.
