[Winpcap-users] ARP problem, works with XP but not with Vista..

Do you see *any* packet with windump? Your machine has IP 169.254.45.253,
which is an automatic address i.e. it's assigned to your NIC when it's
supposed to get an address from a DHCP server, but it failed to obtain such
address. In that case it configures an automatic address, but no default
gateway. And with no default gateway you cannot send a packet to 10.68.23.47
with the normal sockets, because there is no route to that destination.
Have a nice day
