Fixing broken Samba File Share access for Linux hosts after installing the latest version of Windows 10

For the past few weeks I’ve been battling to get my Linux instances to access file shares on my Windows 10 instances over the network. Whether it was Ubuntu, Fedora, or RedHat, the recent upgrades to Windows 10 left my Windows shares inaccessible via Samba. Troubleshooting was difficult as I had nothing to go on exception really ambiguous messages via the syslog (“Failed to mount Windows share: Connection timed out”). After some trial and error it all came down to an undocumented change in how Windows 10 supports the SMB protocol.
