samba - Jun 2020 - Could not access a share as a guest

Hi Group,

I have mentioned the details of the Samba and the Smb.conf.

When I access the the configured share from a windows server 2019 server
machine.

I am getting the following error on the samba server side. Your help will be
greatly appreciated.

NOTE: Tried with "force user (S) & force group(S_ to be that of the
administrator" . That too did not help resolve the issue.
