Two XP pc connected to swtich cant ping ipv6!
 

Hi there.
I have these basic 2 xp pc's connected to each other via a switch and has
10.10.10.4/24 and 10.10.10.6/24 ip address.
They both able to ping using ipv4 address.
But not via ipv6 address.
Example A ping6 ::10.10.10.6 doesnt work but they can ping their own
loopback addresses or their own ipv6 addresses.

Firewall is not enabled under lan properties --> advanced.

Please advice.
