Not that I know of. If this happens often, you're probably better of
with finding an IPv6 address broker. There are a number of these; but I
don't remember them, since I don't need them anymore myself.

Yes, but you need to do it right:

That can't work. You need to specify the link where you want to go the
ICMP echo requests to go out; on Linux, you do that with -I<interface name>;
it appears that on Windows, you need to do...

-s <your Local IP>
fe80 IP addresses appear on /all/ local interfaces, and they're all
within the same subnet. For that reason, the kernel (or the block of
code which resembles the operating system, in the case of Windows)
cannot reasonably autodetect what the interface is you want to send out
from -- so you need to tell it.
That said, this has nothing to do with Router Advertisement. Unless
there's a 2002 address as well on your Windows box, you can be sure it
did not accept the RA. If it does, you should be pinging an IP address
out of that range, instead of the link-local one ;-)
