Windows 10 Azure AD, and PIN Login Causes Issue with Access to Network Resources
Today I encountered a strange issue with one of my clients Windows 10 Professional workstations. I received a call that a user I had just setup could no longer access the shares from a NAS (WD EX2100). I logged into the PC, using the PIN Code the user had set, and I was at a loss, because I setup some Windows Credentials for the NAS, and attempted to connect with the device, and I was receiving an error stating that my Active Directory was not available.
I attempted several of the fixes that most of us are aware of, such as turning off IPV6, and even a registry edit of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation. I even tried a few other fixes that I knew, or read about, but end the end none of this worked.
I then decided to select Sign-in options during login, and chose to use the password for the user instead. After logging in, I immediately went into the File Explorer, and attempted to connect to the local resource by IP (this is the standard procedure for this device) at \\x.x.x.x, and I see the Shares now… I then attempt to map a share, and this too works, so I completed all of the drive mappings.
I then logged the user out of the PC, and logged them back in using the PIN. I again went immediately to the file explorer, and found that all the mappings were still there, and accessible. I also then went to the resource again, and instead of the error I would receive earlier, I was still able to see the shares, and access those which the user had rights to.
