Windows 10 Connecting to Mac OS X (Yosemite 10.10.5) SMB Share

Problem:
I have a machine running Windows 10 Professional and a Mac Mini running Mac OS X (Yosemite 10.10.5).  I can’t connect to my Mac’s SMB share from Win10.

Resolved:
Yes

Takeaway:
On Yosemite 10.10.5, be sure to allow Windows File Sharing

Log Location:
Mac
– Console.app – Unable to find exact log other than to go to All Messages – search for ntlmv
Windows – Didn’t access logs, used secpol.msc, not sure I had to

How I Stumbled Upon the Resolution:
First Stop:
apple.com
This post seems to be about OD users versus Local users.  Not sure if that’s me or not so let’s read on.

Second Stop: macwindows.com
After making the security changes recommended above, I rebooted and tried again.  Nearly the same error message but it’s changed slightly:

From:
digest-service: digest-request: od failed with 2 proto=ntlmv2
digest-service: digest-request: guest failed with -1561745590 proto=ntlmv2

To:
digest-service: digest-request: od failed with 2 proto=ntlmv1-with-v2-session
digest-service: digest-request: guest failed with -1561745590 proto=ntlmv1-with-v2-session

Then:
Changed back to “Send NTLMv2 response only” according to this (I reboot whenever in doubt so I’ve just gotten somewhat used to it with some things).  Well, now we’re back to the original failure message.  Since I didn’t attack this from the same direction, it’s good to be able to come back to a base.  Moving on…

So, then:
I got this from here:

On the Yosemite (10.10) side:
Apple Menu > System Preferences > Sharing

Left pane checkbox for File Sharing > Right side click Options

Checkbox for Share Files And Folders Using SMB
Windows File Sharing, check the accounts you want to be able to access files

Done

I then logged in with the username that showed in that list and…I’m in!
