Cannot access NAS in Windows Explorer
Seems this occurs on the forum regularly, but I have tried all of the suggested solutions and nothing works. I am trying to access the NAS drives from Windows Explorer from a Windows 10 Pro machi...

Unreal... in some vague attempt to reset everything, I just tried changing the password to exactly the same password it already was and everything worked.
The previous password was working for web access and SSH, but for some strange reason wasn't working for SMB sharing... reset it back to itself and bingo!
Thanks for all your help!

Good to hear you got in.
I had a further dig around on my NAS. SMB users are not the same as normal Linux users. The Samba (SMB) module has its own user database. The NAS will have a Linux account for admin, for general administrative purposes, such as WebUI and SSH, etc. Then it will also have an SMB user account for the admin.
Typing this command from the command-line, will show you the SMB users on the system.
pdbedit -L -v
I suspect that when changing password from the GUI, the NAS will change the password for the Linux admin user and then afterwards feed the same password into the SMB admin user via smbpasswd. That way the two passwords are the same, but in essence it is still two different user accounts. I suspect the issue was a "desync" between the Linux admin user's password and the SMB admin user's password.
Cheers

That would explain it - wish I'd understood that earlier and I would have tried a re-sync. I did try turning off SMB and re-enabling, in case it was something similar, but obviously it needs the PW change to re-sync.
Thanks all for helping out!

Yea, I only got to think of it after digging around more on my NAS this morning. But this is almost certainly what happened, though I've no idea why that happened :)

Logged in as root to take a look and interestingly, admin had a Bad Password Count of 0, even though I must have had 20-50 failed attempts, at least, in the past week although database had correct last password change date as today ;-)

For the sake of it, I tried to access with intentional wrong password and my bad PW count for the SMB admin user stayed at 0 as well.
Bad password count : 0
I suspect that this might be because there is no policy against too many bad PW attempts (like lockouts, etc). So, the Samba (SMB) database probably does not count them in that scenario then.
