After the KB-4058258 update my main computer (Dell XPS 8700) no longer communicates with my other windows 10 computers (also updated but working properly) on my ethernet network. The reason seems to be that it now classifies those computers (and my WD Mycloud) as media devices instead of computers. They can see it, but it cannot see them, except as media devices. When the update first installed, in update history it said it needed a restart to complete the install. It had been restarted, shut down and cold booted numerous times.
I went back to a restore point immediately before the update, and everything worked correctly again. Then, windows re-installed the KB 4058258 update, with no errors shown, and the network problems are back.
Is there a fix for this?
