Problem Cause

Citrix 'BNdevice.exe' service is modifying 'TimeZoneInformation' registry key.  

Note : TimeZoneInformation registry keys should not be altered manually. If values are not changed properly (including DST and others),this will end up with system in wrong time zone/ time settings. NLA might fail, one of the parameters to properly identify systems on network is system time.
