RE: BSOD in tcpip6.sys under Windows XP SP3

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!

Whta about Renaming the tcpip6.sys to tcpip6.sys.old in this path:
C:\Windows\System32\Drivers\tcpip6.sys.old
And see if that will eliminate the issue or as I said the Minidumps will
help to pin point what initiating tcpipv6.sys to start and cause this error.

Thank you for suggestons. This is a new installation of Windows XP sp3
(slipstreamed) in a newly formatted partition. The drivers are all up to
date. I have already disabled (external) TCPIP6 in the registry. Apparently,
this does not disable tunnelling ICMPv6 (even though IP6 tunnelling is
disabled).

With Norton firewall, I blocked ICMPv6. Unfortunately, Norton AV kept
deleting inappropriate files, so I switched firewall programs and the problem
returned.

I will have to look into how to tell Outlook to use IPv4. I have already
scanned for malware with four different tools. I will do thorough memory
testing (I havn't done that for a while).

The only other thing I can think of is that I have Visual Studio installed,
and that might replace part of the TCP/IP stack.

Before going to indeepth troubleshooting try the easy way first!
Update the Motherboard driver specially the NIC to the latest stable driver
and Run A thorough scan for malware and Viruses.
Test your RAM for Faulty Bits or bad Bits in memory and see if that will
eleminate those options from the list.
Read the minidumps that can shed some light on the causer, my hunch goes for
this: ntkrpamp.exe which mean bad image.
Disbale the TCPIP6 in the registry:
[-]HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents =
DWORD 0xFF

Or uninstall the Protocol by running this command:
ipv6 uninstall
Or this:
netsh interface ipv6 uninstall
Then Set the Outlook to use the TCPIPV4.
