> Fire an linux laptop up,and plug into your 'clients switch' and do the same two
routines. See if these are identical.This is a starting point. If these appear to
be the same. Fire up Wireshark on the same linux laptop and filter down Wireshark
to an ip address of ONE client ip address you have statically assigned in
dhcp.conf. Fire up the client you have assigned to this IP.This will be a more
granular finding as to were communication stops between server and client.

temporarily.
It's not a managed switch. I'll next be at school tomorrow (They're pretty busy
today anyway with Halloween) and will try looking at this from the client side. In
the mean time, if anyone has any ideas, I'm all ears. I've got to get this thing
working by Monday.
