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.
Not on my Win 10 Pro!
Ethernet only, all SMD versions selected.
Made all recommended changes in Services and RegEdit. Still no go.
Asks for credentials on any attempt to map drive on Win 10 Pro running 20H2.
The Win 10 Home PC can access my OMV NAS without issues.
Something basic is busted. I even checked my Ethernet cable.
At wits end...
Any help is appreciated

Thank you, Microsoft.
also
make sure "CONTROLPANEL\PROGRAM FEATURES \ Turn windows features on or off \
turn on the checkmark to enable SMB 10/CIFS File Sharing Support
Also
allow "WindowsDefenderFirewall\Allow an app or feature through Windows Defender Firewall"
look for "File and Printer Sharing over SMBDirect"
This was the last piece for me. Reboot and works every time now.

Try clean install with 2004 same issue. try clean install 1909 and now smbv1 share work flawlessly
