Network Mount Fail PC to Rpi3

[zeze]

Hi everyone. I am new with Linux and Raspberry. I have just Rpi3. After setup, PC (win 10) can open RuneUI, PC can use SSH for editing. But the problem I have that PC can't mount shared folder to Pi3.
On PC, the shared folder (full): Network/DESKTOP-BLH8B05/Music
On RuneUI NAS mount:
Source name: DataD
Fileshare protocol: CIFS
IP address: 192.168.0.103
Remote directory: Music
Guest access: off
Error: mount error(115): Operation now in progress Refer to the mount.cifs(8) manual page (e.g. man mount.cifs). I have this problem for a couple of days, but can not resolve. I tried write: Music, Music/, DESKTOP-BLH8B05/Music.... but nothing improved.
I am very grateful for all your help.

You can also try to use advanced mount options and set "sec=ntlm" --> You means like this? (following pic). I do it, but the same error (115). Now I try checking again more on share win 10 and Linux mount.
Thks for reply.

I have done Creating the Share on Windows 10 exactly. I have set wifi router static for PC. Smartphone see PC + Rpi3. But NAS mount still failed.
I also try to use advanced mount options and set "sec=ntlm" but still nothing happened.
