Hi Everyone,
>
if anyone within MSFT could contact me on- or off-list about this issue
I would be very grateful.
we run a reasonably large on-campus deployment of ISATAP for Windows
clients in areas where native IPv6 is not possible. This has worked fine
for years and still is. I'm well aware of all the pros and cons of
ISATAP and I don't want a religious debate about using tunnels right now.
A couple of months ago we started hearing about stray Windows update
issues on Windows 8.1 hosts that had ISATAP connectivity. If the host
has native IPv6, VPN-tunneled IPv6 or no IPv6 at all it works just fine.
The issue has now become more prevalent (also with Windows 7) and I had
the chance to debug this issue. The client displays an error code
80072F76 (unknown error)
I'm happy to report that the MSRC (Microsoft Security Response Center)
followed up on this and Windows Update for ISATAP hosts is fixed since
at least September 17th. According to them the fix is not final yet, but
I can confirm that all our issues are resolved.
Best Regards,
Bernhard
