After deployment of update (from 10.0.3.0 to 10.0.3.2) to all devices in the zone, AdaptiveClients on the workstations, which already have recieved 10.0.3.2 can not login to the zone any more. Before the update the same PCs with 10.0.3.0 could authenticate users without any problem. There is no popup from ZEN agent during the windows logon process. Trying to right click over the blue "Z" and say "log on" brings nothing - neither logon dialog nor error. Anyway there is one laptop, which can log on user while having 10.0.3.2 installed on it.The server itself has 10.0.3.2 as well and client on it can log in the user.
