Windows 10: Samba SMB2 SMB3 not working

Hello. I have two NAS boxes in my living room to store and then back up my photos and other media.I like to use Samba so I have a network drive much like I have at work. I have enabled SMB 1.0/CIFS file sharing support, but I was told support for this was going away soon in Windows and that I should shift to SMB 3.0 or higher for security. So, both my NAS boxes are set to SMB 3.0. So, I thought I would be able to turn off SMB 1.0/CIFS file sharing support since I was no longer on that version, but when I do, I can't access my network drives anymore.What's the correct way to configure everythin

How to get SMB2 or SMB3 working

I have Win10 installed, and I have a media player on the network running LibreElec with KODI.

On Win10 I have the Downloads folder shared on the network, and on the Kodi system, I have to change the settings from using a minimum of SMB2 down to SMB1, then manually add the shared folder using the IP address and share folder name. Browsing won't find
it at all. It use to, back when the media server was running Windows as well, but now, not at all.

How... on the Win10 system... do I get it to use SMB2 or SMB3?

 

Samba shares TO Windows 10 now working OK (finally !!!!!)

Hi there
I tried all that stuff to no avail
anyway thanks for suggestion -- it's all working fine now.

In my SAMBA config I have at the start of the GLOBAL section

[global]
max protocol = SMB3
# can set it to SMB2 if you want experimental SMB2 support.
#
workgroup = WORKGROUP
server string = Samba Server Version %v

; max protocol = SMB2

log file = /var/log/samba/log.%m
max log size = 50
security = user
passdb backend = tdbsam
name resolve order = bcast host lmhosts wins


Cheers

How to user SMB2 on Windows?

Hi,

I have a problem accessing my Synology DS218J NAS from my Windows 10 desktop. I get the following error when I try to access it.





The NAS is working fine, as I can access the web portal from the same desktop. I can also access the NAS from other laptops and mobile devices.

I tried using a Linux VM to connect to the NAS via smbclient: "smbclient-U galapogos -L <host>" and I get the error "protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE"

After googling on the Windows/Linux error codes, it seems to indicate a SMB1 error, but I didn't think it would be because both the Windows desktop and the NAS have SMB1 disabled.

But, just to confirm, I tried to force SMB2/SMB3 on Linux via smbclient: "smbclient -m SMB2/SMB3 -L <host>" AND BOTH SMB2/SMB3 WORKED!

So, it does seem that Windows is not using SMB2/3? How do I force it system wide? Or, is there an smbclient on Windows that I can try to use to confirm the problem?

I've already disabled SMB1 in Windows Features.





I've also disabled it in the registry via PowerShell commands and verified that it's not there in the registry.





So, does anyone know how to FORCE Windows to use SMB2/SMB3 like I can with smbclient in Linux?
