In /var.log/nsvpnd.log,  there are errors as below:
[04/25/2018 02:26:20] fs_cmd_put_fileseg: Error writing file on the server: ERRSRV - ERRerror
[04/25/2018 02:26:20] fs_put_process: fs_cmd_put_fileseg() failed
 

Resolution

Try with following workaround:
1. Use Windows Server 2008 R2 and instead of Windows Server 2012 R2.
2. Use Full Tunnel file share access (Windows->run->\\File share path) instead of accessing through vpnd samba client ( via portal mode on Homepage)
 
 

Problem Cause

Windows Server 2012 R2 uses SMBv3 which is currently not supported by NetScaler due to the limitation with SMB library.
 Windows Server 2012 servers configured with SMBv1 are also not supported.
