  Hopefully your application will still allow the user to close it gracefully
when the DB server is
unavailable and restore CTRL-ALT-DEL, otherwise users being focused on
their work will
kill the power switch or yank the cord from the wall to continue.

Not sure which all OS' this works on, but XP definitely, and possibly all :

enable the policy "Remove Task Manager," either in GPEDIT or by
setting the registry entry.

HKCU\
 Software\
  Microsoft\
   Windows\
    CurrentVersion\
     Policies\
      System\DisableTaskMgr = dword:1



For Less than NT (may have undesirable effects such as no task switching):

    // Win 95/98/Me
      unsigned dummy;
      if (!::SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, TRUE, &dummy, 0)
){
        DWORD rc=GetLastError();
       //  for failure
      }
