I used to be able to map an IoT device with a fixed IP address by using "net use X: \192.168.x.xx" and it would work. Long story short, after spending several hours on this, the new 1709 Creators Fall Edition seems to require the root label explicitly as "net use X: \192.168.x.xx\DavWWWRoot" which works (device with Toshiba FlashAir SD card). I have tried this in a cmd window and in a batch file on two separate PCs with 1709 Fall Creators Update. Both act the same. All older versions of Windows (XP, 7, 8, early 10) are able to map a drive without specifying the root name after the IP address.
This behavior breaks scripts that were working before the upgrade.
Does anybody know if this is intended behavior? Is there a good reason for changing this?
