That is really odd. @sam_nazarko is in the moment looking into releasing Kodi 17.4 with the next update which brings some changes to the Samba Client. So you might want to wait for that release or if you are willing to help us testing and not afraid of breaking something could try the current staging version.
Nothing you can break so try it.
Actually just found this. SMB2: Re-implementation of the SMB protocol. Used by Windows Vista and later versions of Windows. SMB2 has sub protocols available. SMB2_02: The earliest SMB2 version. SMB2_10: Windows 7 SMB2 version. SMB2_22: Early Windows 8 SMB2 version. SMB2_24: Windows 8 beta SMB2 version. By default SMB2 selects the SMB2_10 variant
so that would be with SMB2_02 in my case: sudo nano /etc/samba/smb.conf
I haven’t touched the file since August, and a couple of updates came in after that. I do not see the setting that i have set there anymore on my Vero. It could be that one of the updates replaced the file and the setting was removed. Accessing the files from the share still works, which probably means that it should work out of the box now.
Aha, interesting. I have a NAS (LinkStation) that is probably running Linux, but the same rules apply then. So, it looks the setting up for establishing the first connection. Then it is sort of in the “address book” and “auto-dials” from now on. Good to know. Thanks!
