Win10 20H2 fixes the issue.

Previously when 2004 broke smb1, I rolled back.

There was no registry change or any other modification made to the system.  After Win10 20H2 upgrade was installed via Windows Updates;  SMB1 worked as it did before the upgrade.

Thank you Microsoft.

    Why stick to SMB 1? 

    If your NAS is not older than 3-4 years, it should have SMB 3 enabled, and a configuration flag. 

    Check specs of your firmware release or check by command line, see next. 

    Windows 10 SMB Client uses SMB 3.11 by default. 

    https://docs.microsoft.com/en-us/windows-server/storage/file-server/file-server-smb-overview 

    NAS SMB Server runs SMB 1? 

    If you're familiar with accessing your NAS by shell, SSH consider to upgrade SMB Server 3. As easy as editing Registry or change Windows features. 

    Read this how-to in a previous reply of this thread:

    Thanks for your assistance

    SMB 3 is not available on my PC.

    Am I looking in the right place?

    But what if my NAS is 10 years old?

    SMB3 is build-in. There is no option to install/uninstall it.
