  • January patches for Win7, KB 4480970 and KB 4480960, break networking

    Tell me if you’ve heard this one before.

    I first read about it on Günter Born’s site, but word is starting to spread:

    The KB4480970 (Monthly Rollup) and KB4480960 (Security only) updates were released by Microsoft on January 8, 2018 for Windows 7 SP1 and Windows Server 2008 R2 SP1. The updates seem to cause serious network issues for some people. Network shares can no longer be achieved via SMBv2 in certain environments.

    Details in Computerworld Woody on Windows.

    UPDATE: Martin Brinkmann has further details:

    The issue is triggered only if the user attempting to make the connection is an administrator on the machine that hosts the Share. If the user is “just” a user on the device that hosts the share, the connection should be fine.

    (Some of you ask why I quote Günter and Martin so frequently. Ends up, they’re in the right time zone — they get the bad news before it’s circulating widely in the US — and they both have excellent eyes for screw-ups. Of which there are many.)

    ANOTHER UPDATE: It’s possible that this is another manifestation of the oem<number>.inf issue that’s documented in the KB article — the same bug that’s been acknowledge by MS since April. But the descriptions I’m seeing are different. In particular, Brinkmann’s description above doesn’t sound anything like the oem<number>.inf NIC failure.

    Anybody have more details?
