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

I have application running on XP and I have added IP address
manually with arp command like this:

   arp -s aa-cd-ef-12-34-56

Now when the application sends UDP packet to that IP address
I see it with WinDump.

But when I try the same application under Vista I don't see anything
with WinDump.

Running "arp -a" gives about the interface in question:

   Interface: --- 0x10
     Internet Address      Physical Address      Type           aa-cd-ef-12-34-56     static       ff-ff-ff-ff-ff-ff     static            01-00-5e-00-00-16     static           01-00-5e-00-00-fc     static       01-00-5e-7f-ff-fa     static       ff-ff-ff-ff-ff-ff     static

And the application is certainly using interface
to send to destination
