The logon logs, PC shutdown logs, PC suspension logs will not be sent to the server immediately. They are saved on the local disk first and then sent to the Management Server. It may take some time before the logs can be searched on the log viewer.
If the power of a PC is cut off by force, the logoff log and PC shutdown log will be created at next start of the client (CT). Therefore, it may take some time before the logs can be searched on the log viewer.
If the power of a PC is cut off by force at the moment of logoff, two logoff logs for the user may be created sometimes.
Under Windows Vista® or Windows® 7, the logoff logs of all logon users at the time when power of a PC is cut off by force will be recorded.
