Dear In my domain environment I recently changed the KMS host from server 2008 to 2012R2 its activating windows 10 and then I installed the script fro activating office 2013 and 2016. the issue is that its only activating workstations that are joined to the domain if the workstation is not part of the domain (but still within the same network) its not activating it with the below error I checked and re-checked the time sync and its correct and there is no firewall in between the two systems.
