Cannot Access Windows Network Shares

Three machines:
Surface Pro 4 - fully updated
Surface Pro 3 - Windows 10, fully updated
Lenovo X220T - Windows 8.1 Fully updated

• All three machines can see all available network devices, including each other.
• All three machines can successfully access and interact with third party network devices. In this case, it is a NAS and a network printer.
• The windows 8.1 machine can access each of the other windows 10 machines
• Neither Windows 10 machines can access any other windows share on the network.
  
  • This gets me error 80070035 with diagnostics telling me nothing
  
  
• All three machines are on a Homegroup and while each can see, no one can access anything

Trouble shooting tried:

• Double checked all sharing settings on all three computers. They are identical.
• Double checked workgroups
• Tried it via IP addresses
• Reset winsock on all machines
• Flushed DNS on all machines
• Reset the router
• Uninstalled and reinstalled Windows sharing and about 3 other network protocols and services
• Enabled NetBios
• ran this: sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
  sc.exe config mrxsmb20 start= disabled
• Messing around with all sorts of netsh commands clearing and flushing all sorts of other things

I'm fresh out of ideas. Any thoughts would be helpful.

Set up a local account for all workstations instead of the email account for a login name.

Thanks @play. Is that a solution or a test? I ask b/c that is not a configuration that I can live with long term. That completely avoids the issue.

It's a workaround until Microsoft resolves the issue...to the best of my knowledge.

This is the best info on the problem and coming fix:-

Cannot connect to CIFS / SMB / Samba Network Shares Shared Folders in Windows 10 after update 1511/10586

@play So anyone who uses connected accounts can't share files between windows computers? Wow.
@linw thanks. This was in my archive. Very helpful.
