Access to dwsync.xml was denied using Raspberry PI and Win 10 SAMBA

I have a Raspberry PI running LAMP on my local network.  I have SAMBA configured in both my PI and my Win 10 desktop.  I can browse the file system, on my Pi, from a Win 10 File Explorer, but Dreamweaver can't seem to do the same. 

I my PI is called "GOLLUM" and, in the Win 10 File Explorer I can access the PI using the following:

\\GOLLUM\some_dir

In the Dreamweaver Site\Manage Sites dialog box, when I edit the "Site" I have set up, I navigate [by clicking the little Folder Icon] to the directory, on GOLLUM, where the "Test Site" code resides.  And, when I click "Save"\"Done" there are no complaints.
I've also tried using the static IP address, and even attempted using "localhost", though I don't know what I doing, in that case.

Nothing works.  I get a 404 error page in the preview pane.

And, when I click F12, I get the following error message:

"Access to \\Gollum\path\_notes\dwsync.xml was denied."

Any ideas?
