I'd still recommend that as a debugging method, but one other
potential
cause is that Win10 now disables remote access to the administrative
shares by default. They can be specifically re-enabled, but without
doing so, would generate an access denied error no matter what
credentials were used.
I tried the debug level at 3 (the highest recommended for mere
mortals) and found nothing educational.
I rebooted my workstation to CentOS 7 and tried smbclient and it, too,
failed, so I guess it's the remote access problem. Does that mean
rsync won't do any better than smb or does rsync get past the remote
restrictions?
Any clues on how to enable remote access? I'm not concerned about
security since we're behind a good firewall.
Cheers,
This is how to enable remote shares:

This is how to enable older versions of the smb protocol:

Though to answer your question rsync doesn't rely (or is aware of in any
way) the default shares, and it doesn't use the smb protocol, so you
wouldn't have these problems. You may have a different set of problems,
mainly revolving around getting permissions and modules right, and (if
you use it) properly engaging shadowing. That said, SMB can't use
shadowing at all, so I see rsync as a major improvement in many ways and
use it for all my windows systems.
