That solved this issue and moved ahead of that IPC$ share access issue. Thanks for that.
Now, I am seeing the below error.
Please note I am new to samba world. Pardon me if I am asking for more.
Meanwhile I too will check smb.conf online doc and my smb.conf for any conflicting configurations.

CAUTION: This email originated from outside of the organization. Do not follow guidance, click links, or open attachments unless you recognize the sender and know the content is safe.
The "restrict anonymous = 2" setting in smb.conf is what (most likely) causes the mapping to IPC$ to fail as guest.
As an experiment, u may want to set it to 1 (restrict anonymous = 1) and try. What that means in terms of security, you can find in smb.conf man page.
Hope this helps.

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.
