Win10 AllowInsecureGuestAuth or Win10 logon mapped to unRAID user

[Zan]

I've been trying Win10 with Argus TV but recording to unRAID shares isn't working as Win10 disables unauthenticated SMB share access by default see here https://techjourney.net/cannot-connect-to-cifs-smb-samba-network-shares-shared-folders-in-windows-10/)

 

The AllowInsecureGuestAuth regeditworkaround hasn't worked either, so can someone help with the other option, which is to create a Win10 logon that maps to a specific unRAID user?
