ReadyNAS 204 - Access Denied after Windows 10 update

I have been using a ReadyNAS 204 for a few months with no problems. My system has two Windows 10 (64bit) computers connected to the ReadyNAS.  A few days ago, one of the computers received a Windows 10 update to version 1703, OS Build 15063.447. My scheduled backups no longer work. Doing a bit of checking, I find that when I go to the settings on my ReadyNAS Backup page, and do a "Test Connection", I get an "Access Denied-Invalid User Name or Password".  This is true for every backup on the Windows 10 updated computer.  The second computer has not yet been updated, and the "Test Connection" works for the backups on that machine (as do the backups themselves).  All of the share information on the updated computer appears correct.  I have rebooted both the NAS and the affected computer to no avail.

    Thank you StephenB for your comment about checking access.  I started doing as you suggested, and somewhere along the line noticed a  comment about "Password Protected Sharing" being on, and how if I wanted to change that I had to use the "Network and Sharing Center."  So I went there (to the "Network and Sharing Center") and started looking around.  I eventually got to the "All Networks" area and found the "Password Protected Sharing" area where, lo and behold, "Password Protected Sharing" was turned on.  So I turned off "Password Protected Sharing" and guess what?--my backups now work!!

     

    So in a nutshell, the Windows 10 update apparently turned on "Password Protected Sharing" and the only thing necessary to fix the issue is to turn it off.

     

    Thanks to all.

    I'm not 100% sure, but you might need to enable the SMB1 server functionality on the updated system.

     

    Perhaps check the windows features for the old and new win10 systems, and see if that's the issue.

      Thanks for the suggestion.  The SMB 1.0/CIFS File Sharing Support was enabled, so I turned it off (just to try something).  It made no change, so I turned it back on.  I did forget to note that I created a Windows Credential for the NAS204, and that made no difference either.

        Some further information:  From both of the Windows 10 computers, I can access all of the files on the NAS with no problems,  It's only when I try to do do backups (or use "Test Connection") that I encounter the "Access Denied" problem.
