Ipv6 ping problem

I'm unable to ping my own link-local address in Windows XP SP1 on my laptop. On my other computer it works fine.

Sorry for the Swedish version of Windows.

Does anyone have an idea why I'm having problems? I've just reinstalled ipv6.

Perhaps I should add that my laptop uses home edition and the other computer is using professional.

Maybe you unknowingly set a firewall to block pings?

Well, there could be some setting with that particular adapter (my network adapter).

::1 works but that address is on the "Pseudo-interface for loopback", not my network adapter.
