after updating to zcm 11.3.1 the windows 8.1 user can login once.
after login out he can not login because "the group policy client is preventing login".
maybe with a second time or a reboot he is able to login to workstation.

any clue?

tryed this on a sysprepped machine with the latest windows updates and also on older installation.
every time trouble after installing 11.3.1 even on a clean installation.
