Windows 10 Install: no longer able to access NAS shares

Hi,

 

I upgraded 3 days a go to Windows 10 Enterprise build 16299. It was an installation from scratch

I sadly have no longer access to any of my SMB shares. Access was working on Windows 7: see image below

 

 

 

- I tried dropping to SMB1 in SMB Application + reboot both PC and NAS: no success

- I disabled IPV6 under LAN adapter in Windows 10: no success

- I enabled every sharing option under Windows 10 for both Private and Public networks: no success

 

Using cmd in admin console to map the network share:

 

net use * /delete
net use t: \\nas-ip-address\data /user:admin nas-admin-password

Under the shell cmd, I have access to the shares and their listing through drive T:

However, it is wired that Explorer GUI cannot access to the T: drive. So I still cannot see my shares in GUI

 

 

Under Explorer, I can see the NAS:

- under "Media Devices", and brows the DLNA folders

- under "Storage", double clicking brings the NAS web admin GUI

- under "Computer", named correctly "NAS-01": but if I try to access the shares it gives me a "Network access error"

 

 

I attach above the image with my error

Please help me fix this asap, I am lost and really need the SMB access to manage my backups

    I managed to access the shares by doing the following in NAS web GUI:

    - Accounts/Users: I created a user with same credentials as the PC-USER I am logging with under windows 10

    - I assigned the created user to a group allowed read/write

     

    Now, I can access my NAS shares under windows 10

     

    However, for me, this is not a fix.

    Under Accounts/Authenthification, I have "Account type" set as "Local Users".

    I need, even if not recommended, to access the NAS through the NAS local admin account. The way I do it know is not possible.

    Also, ehy windows 10 is not able to negociate the prompt for user/password when accessing my NAS despite I set the "Authenthification" to "Local Users" in NAS

     

    For me, it seems clearly an issue with the NAS and how it is exposing things to windows 10

     

    PS: I am under last OS 6.9.1

  • I have a hint:

    [2017/12/26 17:27:59.473697,  2] ../source3/auth/auth.c:332(auth_check_ntlm_password)
      check_ntlm_password:  Authentication for user [PC-Username] -> [PC-Username] FAILED with error NT_STATUS_NO_SUCH_USER, authoritative=1

    Where PC-Username is my login to windows 10

    Seems like windows is not able to ask for a local nas user name instead of the windows name

    Under my NAS, it was always configured to accept only local users

     

    My Android devices have no issues to access the shares

    Windows 7 was able to prompt for the access password
