Explanation
The problem is located in the file transfer between Windows 10 and your NAS. Filesharing between Windows and a NAS is using the SMB protocol. There are different SMB levels. In a simple way: the devices on both sides of the network cable need to use the same SMB level.
Solution Synology NAS
- Logon to the DSM > Control panel
- File services > Tab SMB/AFP/NFS
- button Advanced settings
- set Maximum SMB-protocol: SMB3
- set Minimum SMB-protocol: SMB2
- Apply
- Reboot the device
Solution Windows 10
As from Windows 10 version 1703 SMBv1 is no longer supported. SMBv1 needs to be disabled, otherwise Windows might try to use it. After a Windows Update the SMB1 might be activated back again. By adding four values to the Windows Registry, the SMBv1 and an SMB cache are disabled permanently.
- Download the attached Audisi_Registry.txt and rename it to .reg (click the + at Article attachments)
- Always create and store a backup of the registry (or just the HKEY that will be affected) to restore the previous state in case of any problems.
- Execute the Audisi_Registry.reg
- Reboot the machine
