Activation Error Code 0xc0020036
My workplace has a volume license activation code for Windows 10 Education. We just started slowly installing and deploying images on our computers early this year when the Anniversary Update was the current release. Most of our computers didn't start receiving the 1709 Creators Update until July and August, but that didn't really affect computers deployed with this image.
Today, when the Fall Creators Update was released through Window Update, we installed it on two of our computers that hadn't been assigned to anyone yet. In the settings, under the Update>Activation section, it showed the last 5 characters of our volume license product key prior to the Fall Creators Update. After the update was complete, both of these computers showed that Windows was not activated. After the upgrade, the last 5 characters of the product key was changed to the same sequence of characters on these two computers, but it is completely different from our actual volume license.
When we enter our product key to try to reactivate Windows, we get error code 0xc0020036. We have probably around 75 Windows 10 computers deployed throughout the company with this volume license. It is looking like they are all going to be deactivated. Does anyone know how we can resolve this, or is it possibly a temporary issue with the activation server that will sort itself out? At some point when trying to troubleshoot the issue, the computers give a message about trouble communicating with the activation server and to make sure the computer is online. Both computers are able to connect to the internet with no issues outside of the activation process.
