The registry key 
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\CachedLogonsCount
is non-null. It means that the remote host locally caches the passwords
of the users when they log in, in order to continue to allow the users
to log in in the case of the failure of the PDC.


Solution : use regedt32 and set the value of this key to 0
Risk factor : Low";
