I already tried renaming tcpip6.sys. That broke both Outlook and Norton AV
(strangely, the OS didn't complain). I have checked that the file is the
correct version, etc. Ideally, I want to use IPv6/Teredo for some other
things (but I can give them up).

I have the Eset firewall locked tightly against IPv6-ICMP (as they call it).
I had forgotten to add a separate rule to deny ICMPv6 addressed to localhost
(::1). The last crash didn't leave me a dump file. If it crashes again, I
will definitely use the dump to try and figure out what is happening. Now, on
to memory tests!

So install Norton Firewall without the AV if that will help solve the
problem.

Visual Studio should have nothing to do with the ipv6 stack.
