None of my three Windows computers can access smb

It works perfectly with a Linux PC and Android smartphones.

Error message

\\192.168.1.132 could not be accessed.

Other shares work perfectly.

What could be the problem with the Win 10 computers?

i think then you see the smb server under your windows!

Unfortunately, it doesn't work either.

It works fine via SSH.

It also works fine with other Linux devices.

Now I don't know what to do, maybe it's LibreElec 9.2.7?

If I specifically specify the share folder

"\\192.168.1.132 \Backup" it works.

Is that correct?

But I want to see all the shares at once.

When I mount from my Ubuntu server from console the same thing

mount -t cifs -o username=xxx,password=xxx,uid=1000,gid=1000,file_mode=0660,dir_mode=0770 //192.168.1.132/Backup /mnt/usb

Without specifying the shared folder there is an error message

root@hp-server:~# mount -t cifs -o username=xxx,password=laurent,uid=1000,gid=1000,file_mode=0660,dir_mode=0770 //192.168.1.132 /mnt/usb
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg).

dmesg | tail

[354809.070673] CIFS: Attempting to mount //192.168.1.132
[354809.070678] CIFS VFS: Malformed UNC in devname.

I also find it strange that it does not work here.

But I'm glad that I can at least mount the share individually.

Thanks for your time
