DEMdev Thanks for responding.
The only message I see in the application event log is that ImmidioFlex+ service has started.
Just to correct my previous statement, it looks like DEM is working partially after a user reboot. E.g. I can see desktop shortcuts (including DEM User Environment Refresh) is created. But there are no drives mapped or ADMX settings applied.
If I run flexengine.exe -UEMRefreshDrives, drives appear. Also if I run flexengine.exe or DEM User Environment Refresh, logs are created (debug logging is enabled for the user). But no logs are created upon user login after a reboot event
The issue is seen if the user reboots or shutdown the machine. Issue is not seen after a user logoff or if the desktop refreshed via Composer and then logged in.
