Log in requested for samba shares in Peppermint

Hi something strange.

Set up shares on my peppermint laptop with anyone can access.

Can see the shares from my mint 19.3 desktop but when I try to access from the desktop a password is requested.

I tried entering the user name and password for the laptop and for the desktop but can not login.

In the other direction on problems accessing shares on the mint system from peppermint.

Any suggestions would be welcome.
