    After Win10 update to Ver 1607 x64, can no longer access NAS

    Windows 10 updated to Version 1607 and I can no longer access my Synology NAS. I have attempted every potential solution I have found on the net to no avail. I have another machine running WIN10 that I disabled windows update on and it's at version 1511 and the NAS is accessible. I called Microsoft support and the tech told me he had no way to trouble shoot this problem. Synology has gone over the top trying to help me with a solution and so far we have been unsuccessful.
    Can someone point me to a fix. This is my business machine and I cannot access files I need.

    Click on the start icon. Start typing Credential. The top app entry on the list should be Credential Manager, click on that. Click on Windows Credentials, then Add A Windows Credential. If you NAS has a fixed IP address, I would use that for Internet or Network Address. If the NAS is using DHCP then use the server name of the NAS. If your NAS is setup for users and passwords, then insert the username and password for the account on the NAS. Otherwise, any name should work and a blank password. I use my Windows user account name. Save it all and that should restore access.

    I have the credential in the system. I have tried numerous credentials to no avail. NAS has a fixed IP on the network.
    Attached images:
    Map Drive Error Normal Login1 < attempt to map a folder on the NAS
    Map Drive Error Normal Login1 error < error I receive. NAS is fully functional on the network, 2nd PC with WIN10 sees it fine.
    Map Drive Error Normal Login2 < attempt to map a folder on the NAS using different credentials
    Map Drive Error Normal Login2 cred < NAS User and Login
    (limited to 5 uploads)
    It asks for this same screen a second time, then asks for permission with my Microsoft Account twice, then fails.

    As noted originally, I have attempted every "fix" I could find on the net with zero success.

    PS Thank you for your service, it's very much appreciated.
