a crossover cable?  I would assume that the wiring in the school goes to
a hub of some type that takes care of "crossing" the wires.  Using the
same cable to connect the two computers won't work.  Pin 1 is connected
to pin 1 in both computers etc which means that transmit is connected to
transmit.  If you can't find a crossover cable, you need a hub.
