I have discovered a possible bug with Multipoint 2016 and the VirtualIP feature (i.e. "Assign a unique IP to each station"). When the VirtualIP feature is turned on with Multipoint 2016, almost every time I log out of Windows (USB or direct-connect) my network goes offline as well so that all stations stop working. I sometimes see a yellow exclamation mark on the network icon in the taskbar, while sometimes it shows a red x. A screen on the direct-connect station says "The connection has been lost. Attempting to reconnect to your station... The network is not available. The connection will be reinstalled when the network is available." After a couple of minutes the stations come back to life but then most often a yellow exclamation mark appears on the network card icon with the tooltip of "No Internet Access." When this happens, Internet and other network resources no longer work and my LAN stations no longer connect. Pinging the computer from the outside doesn't respond, but the USB and Direct-Connect stations can at least log in.
When this happens my IP is 169.254.45.3. When I ran IPConfig /renew in an elevated command prompt I get the message: "The operation failed as no adapter is in the state permissible for this operation." I updated my network card drivers but that didn't help. I set my IP to static but that didn't help. When I go to the properties of the network card I sometimes get "an unexpected error occurred" but then my second try it lets me in.
Rebooting solves the issue but ironically disabling my network card also solves the issue. When I disable my card, it freezes all of my stations but then after a couple of minutes everything comes back to life and the network card is enabled and functioning again. I assume it's the MultiPoint Repair service that is recovering my network card for me.
Disconnecting doesn't cause the issue. Logging out does. Is anyone else having this issue? Is there a solution other than turning off VirtualIP? I am pretty sure it's the VirtualIP with the issue, since when I turned if off during my troubleshooting I was able to log off without issues and when I turned it back on the issue came back immediately.
