Gratuitous ARP on Vista?

Hi Experts:

I have noticed some differences on Windows Vista regarding to the gratuitous
ARP: I have a virtual adapter, under Windows XP, when IP Helper function
"IpRenewAddress" is called for the virtual adapter, gratuitous ARP packet is
generated by the system; but under Windows Vista, this seems is not
happening. Does this make sense? Can this be explained?

Thanks in Advance!

Probably because the entire TCP/IP stack of Vista is new from the ground up.

Windows XP's network stack is a bit old (I think it came from Windows 95, or
at least Windows NT 4.0), so the ARP packet may be an older, no longer in
use functionality.
