In addition to this, don't forget you can always use Ethereal:

or, as it's now known, wireshark:

to capture a sample of the traffic and see exactly whats happening when
the "flashing" occurs at the switch. Though it is a switched network,
broadcast packets should be visible to any PC connected to the switch.

If the problem is not broadcast oriented (however, having *all* lights
flashing in unison on the switch would tend to indicate this) and your
switch is managed, you may be required to designate a "sniffer" port to
echo the traffic from the server port to the port where your sniffer
(i.e. wireshark) resides. :)
