Hi,

I use mapped drives too, and found this same issue in Windows 10. Found this solution:

1)Write the bellow lines in a mapped.reg file then run it:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"EnableLinkedConnections"=dword:00000001

2) Restart your computer.
