[@TK] After trying this and only applying the host file patching with telemetry servers to block them… next time I accessed a program on my mapped network share on my LAN I got a warning from windows that the location was not on my LAN and did I really want to access it… after a little investigation I found something changed my default wifi connection to a PUBLIC network instead of it’s previous setting which was PRIVATE! The only program I had run in the interim between shared mapped network drive access that messes about with systems internal settings was this! I cannot conclusively prove this software messed with my system without my consent but it’s the prime suspect…
So if your mapped network drives suddenly start warning you about accessing a location that is not on your private LAN at home or work, check the network connection to see if some badware has changed it from Private to Public without your permission… If you can repeat the software messing with your critical network settings without consent report it to where you got the software from and maybe submit the software to Microsoft windows defender team to consider warning/blocking the badware from running.
