Enable "ping6 ff02::1"-replies on Windows XP SP2

Hi all,
I have a Windows XP SP2 host on my localnet. When it comes to IPv6 it works great, except for one thing:
I have enabled everything about ICMP in the firewall, and I am able to ping the host, and the host is able to ping everyone else on my network. However, when I ping ff02::1 from the Windows-host, the replies from the other hosts are blocked by the firewall.
Does anyone know why? Or better yet, how to unblock this?

You're trying to ping a link local address - it's necessary to tell the OS on which interface this IP is to ping since link local addresses are - _link_ local! :)
Use
netsh interface ipv6 show interface
from the commandline to get the interface index of your desired adapter. Then ping the address on the link by
ping ff02::1%3
where '%3' defines interface index = 3 in this example..

for same explanation..

On Linux use something alike 'ping6 -I ethX ff02::1'
('-I interface' to tell the interface)

netsh firewall set icmpsetting all enable
Should do the trick, that is what AICCU executes too
