On the main tab, I was notified that the USB was CORRUPT, so I replaced the USB. I burned UnraidOS on the new USB with a tool DL'd from the website and copied the config folder of the original USB. Everything is working fine since boot, only I can't access it via SMB, not from Windows 10 PC, not from iOS devices, etc. The network tab in Windows shows the Unraid server, but when I click on it, I get 0x800070035 . I have read and tried several posts on the forum about SMB (e.g. the following), but no luck.

You have the same set of errors and Samba is not starting.

Shutdown the server.  Pull the boot drive and plug it into your PC.  Then run chkdsk on the flash drive.  While you have it in the PC,  go to the /config folder and  rename (or delete) all four of these files.  (add .old as a suffix will accomplish this.)

 

You will have to setup your root user password and the Share Access users again. 

 

Do a back up of your Flash Drive using these instructions:

 

         https://docs.unraid.net/unraid-os/manual/changing-the-flash-device/#back-up-your-usb-device-using-the-unraid-webgui

 

This will have the benefit of verifying that these files can be read.  

At first, I used Dynamix file manager (webGUI) to save these four files to a separate folder and then rebooted the system, but the SMB connection did not work. However, as advised, I unplugged the USB, deleted them, and rebooted again, and was able to connect via SMB without any problems. Thanks super much for your help.

I deleted "passwd", "secrets.tdb", "shadow", "smbpasswd" for someone who will read this later.
