I ran the 10.2.2 update, we were at 10.2, and things were looking good until users tried logging in. The workstations now get the zenworks login window and users are unable to actually log in. If we unregister and register the workstation they are able to log in, but no policies are pushed out. Any ideas why this might have happened?

We only have this one lab running ZCM and were looking to migrate from ZDM 7, but so far our experience has been very poor. Any help would be greatly appreciated.
