Hello DinoMuhic,

Thank you for your tests!

So,

1) Synology - DSM 6.2.4-25556 Update 7
2) Windows 10 Pro 22H2 (19045.4046)
3) Yes (I mean map network drives are automatically mounted at PC launch)
4) Automatic Windows Update are disabled. (but my issue is not new, so on previous windows build too)
5) No
6) SMB (maybe not... see my EDIT below)
NAS: SMB File services advanced settings on NAS: Minimum SMB Protocol: SMB2 // Maximum SMB Protocol: SMB3 // SMB Range: SMB2, SMB2 and Large MTU, SMB3
PC: I don't know where I can see my SMB version...

EDIT: In the "Resource Monitor" app on my NAS, I can see that my PC (also my mac) have a CIFS connection type...

Thank you for the details. Based on your setup, here are the next steps to help troubleshoot the issue:

- Update Synology DSM – Please update your Synology firmware to the latest version available, as newer versions often include SMB compatibility fixes.
- Install Windows Updates – Even though your issue existed before, ensuring Windows 10 is fully updated can help eliminate any potential OS-related SMB issues.
- Provide a Screenshot – Please send us a screenshot of your NAS SMB settings to verify the configuration.
- Confirm Windows SMB Version – You can check which SMB version your Windows PC is using by running this command in PowerShell: Get-SmbConnection
This will list active SMB connections and their version. Please provide a screenshot or the output.

Let us know once you've completed these steps, and we’ll assist further.
