After installing Docker for Windows on my Windows 10 Enterprise (1607) machine, I can no longer authenticate onto the 802.1X-enabled wired network.
This seems to be related to Docker for Windows's dependency on Hyper-V. Disabling the Hyper-V Virtual Ethernet Adapter in Device Manager makes authentication work again, and the connection keeps working if I then enable the Hyper-V adapter again. So that seems to be an effective workaround, though not very convenient.
Does anyone know of a real fix for this issue?
