After pressing Ctrl-Alt-Delete and locking the workstation, Ctrl-Alt-Delete does

As the title says, from time to time after a user locks a workstation, pressing Ctrl-Alt-Delete does nothing! Therefore the user can not get back on the system. The only way to get back on it is to power it completely off and back on.

    Easiest way to lock a computer and get it to unlock is use the screensaver password system... works every time.

    Sorry, I forgot to mention that these systems are in a large corp environment with several employees needing to access the same systems. The screensaver timeout/password is not an option.

    We use to about a year ago, but we have now migrated to Active directory.

    Another product we are running is called Imprivata OneSign -Single Sign-on (It's a Password manager). When it installs it replaces the MSGina.dll entry in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GinaDLL) with it's own authenticator. (SGLaunch.dll)
  5. Best answer

    As it's only an occasionaly problem, I can't help wondering if it isn't down to the individual workstation's power saving options rather than just the screensaver setting. If the system has powered down on instructions to halt the hard disk after, say, 30 minutes, that would be enough to block Ctrl/Alt/Del thereafter.
  6. As it turns out, we have identified the problem to be related to the Imprivata Single Sign-on product we are using. The vendor is currently working on a solution.

    I want to thank everyone for their input. :hello:

    You're wrong.
    XP screensaver password protect does not work every time:
