Network-Share: Access denied

[admin]

I tried to backup from a win-10-machine to a network-share on a win-11-machine and got the message:

Access is denied. (0x0862000900000005)

Sytem-, partition- or file-backup - no difference.
The target is a usb3-docking-station which I can reach without any problems from every point in my network, even from my android-tv, my phone or an old XP-machine. And yes - I granted full access to everyone at the target.

Backing up from the same machine with the last available Macrium Reflect Free works like a charm with no problems.

Any ideas are welcome!

Please delete the NetConnect.db file in the bin directory under the Hasleo Backup Suite installation directory, reboot the computer and try to connect to the remote shared folder using an account that has full access to the remote shared folder.
