Hi,
This morning I became aware of the fact that one of our two NAPs (Windows Server 2012 R2) refused to authenticate client machines through our switches -> 802.1X, computer certificate based authentication.
From the logs: Microsoft Windows security autiting | Even-ID: 6273 | Code 16
The machine in question has just installed the update KB4025335 tonight and seems to have this problem since then. The other machine did not install this update so far and is still working properly. Given the fact are there is a couple of of NPA related things mentioned in the description of the update, I guess Microsoft did screw up something.
Is anybody else facing this problem since the update?
Best,
