To be specific the latest issues can be seen by the snippet below on the Freefilesync log.  Im trying to dial in the symlink operation, and any other remaining errors.

Hmm, it looks as though your application uses some exotic functions
which aren't supported by Samba at a protocol level:
- https://msdn.microsoft.com/en-us/library/aa363866(VS.85).aspx
- https://msdn.microsoft.com/en-us/library/aa362511(v=vs.85).aspx

Please capture network traffic, once with the application running
against a Samba server, and once against a (recent) Windows SMB2+
server:
https://wiki.samba.org/index.php/Capture_Packets

When you have the captures, please create a bug at bugzilla.samba.org,
and attach them there.

You should obtain these captures in an isolated test network, with test
data - they may be seen by others.

Cheers, David
