You solved this before for me:
*"- Accessing NFS shares does not work out of the box on Windows. You
have to install the NFS feature in Windows first: Control Panel ->
Programs and Features -> Turn Windows features on or off -> Services for
NFS"*
I updated to *Windows 10* and the seem to be broke again.
Is that possible?
