Subject: [ntfsd] “ACCESS DENIED” in user mode accessing event created by
IoCreateNotificationEvent during DRIVERENTRY()

hello all,
I use IoCreateSynchronizationEvent(…) in system process ( driverentry()
time ). when I try to open this event in usermode using
OpenEvent(…EVENT_ALL_ACCESS…) it fails with “ACCESS DENIED”. I tried
ZwCreateEvent(…EVENT_ALL_ACCESS…). still no luck. I think it is
something to do with security issue, i.e creating an event “before” logon
and trying to access it after it. So how to make this scheme work?? should i
try some flags like STANDARD_RIGHTS_ALL etc?

thanks & regds
