My problem has the same error described in this thread but it is behaving defferent:
https://social.technet.microsoft.com/Forums/windows/en-US/ab9340b5-846f-4b75-921d-8442c8540bb6/problem-with-accessing-a-windows-share?forum=w7itprosecurity

I am using a laptop and a PC (both Windows 10). I think the problem is on the PC but I'm not entirely sure

I have shared a folder on the PC and when accessing it from the laptop it gives the following error:

"\\servername\sharename is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

A device attached to the system is not functioning"

It gives that error only once. Every subsequent time I try to access the share it asks for me to enter network credentials.
My credentials don't work... Both devices are of course signed into the same Microsoft account with administrator privileges. The folders being shared are owned by and shared with that Microsoft account in the Advanced Sharing/Advanced Security menus with full access. File Sharing/Network Discovery are turned on for both computers on private networks ect..

The only way to see the error again is to unshare and reshare the shared folder on the PC, again it will show the error only once, and then send me into the credential loop.

The PC is able to access the share on the laptop no problem.

The PC has been accessible from the laptop before, I am not sure what happened

The thread above recommended trying the access the shares using ip (\xxx.xxx.x.xx\share) so i tried that and had the same problem but again it worked fine accessing shares on the laptop from the PC

Things I have tried:
• Reinstalling network adapter drivers on the PC

Windows for business Windows Client for IT Pros Networking Network connectivity and file sharing

    What you said worked, I used a local admin account and shared that account's Documents folder, then used that local account's credentials when connecting from my laptop and it worked. The thing is I don't really want to have an extra account on my computer just for this. I would consider this a clue to what is going wrong but not a solution

    don't really want to have an extra account

    Your MS account should map to a local account. Log on and open a command prompt. Run "whoami". Verify that that account or a group that it is a member of, like Authenticated Users, has access on both the share permissions and the NTFS folder permissions.

    Are you the same name on both systems?

    Info from both devices appears to be correct, am I looking at the right things?

    oh and to reproduce it working properly with the local account like you suggested all I have to do is add the local account to the list of people shared with
