I'm trying to find session duration of a user on a domain controller.When i logon instead of a single 4624 event two 4624 events
are generated.Both has different logon id.One has some valid LOGON GUID while other has all zeroes in GUID.All session activities happens with the logon id of event which has zeroes in guid.When i logoff only one 4647 and two 4634 happens.Any explanation for
such behaviour?
