Issue

Trying to mount a share located on a Windows 10 PC from Ubuntu WSL (Windows Subsystem for Linux)  running on Windows 11 machine:

sudo mount -t cifs //192.168.1.25/Data /mnt/WinShare -o username=lin,password=Some$Psw@55

The operation fails with the following error:

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

I checked Windows Security logs on the target Windows 10 PC, and for every mount attempt, there was Event 4625 - Logon Failure - Unknown user name or bad password.
This made it clear that Ubuntu was connecting and communicating with the Windows 10 PC, but for some reason, Windows was not accepting login credentials.

Synology DiskStation 415+ NAS failed. Blue power button LED keeps blinking. Status LED is off. All 4 disk orange LEDs steady on (there are only 2 HDDs installed). Removing all hard drives doesn't change anything. Replacing RAM doesn't change anything either. All this indicated motherboard failure. Owner asked to recover data from hard drives.
