In the last month, we have been running into issues with Windows 10 and domain accounts. It happens if there is a computer that has MULTIPLE user accounts logged in, and the pc sits idle and goes to the screen lock. When a user comes back to the pc and clicks on THEIR user name, and tries typing their password, it will say "incorrect password" right away. After so many tries, it then locks out the "last logged in user" and not their own. We can confirm via the logs, that even though it shows their picture and username on the screen, according to the logs it locks out the previous user. The other weird thing about this is they can click on "other user" instead of their name and login fine. Also, a reboot fixes the login issues but will eventually happen again if multiple users stay logged in. At first I thought this was tied to only Windows 10 version 1709, but I had a Windows 10 version 1703 happen today.
We have a simple domain controller setup + backup DC setup on a 2008 functional level. We have mostly 2008 and 2016 servers, majority are windows 10 workstations. We're a medium sized business.
Anyone else experiencing this issue? Any help would be appreciated. This is my first post on experts exchange, looking forward to giving this community a shot!
