Creating named events in S03

NTFSD
1

Hello,

I’m seeing some odd behavior with named event objects in Server 2003. I have a user-mode app that creates named event objects that do not appear in the base named objects listing (using winobj) in S03, although they do appear in XP and W2K. As a result my filter driver ends up creating event objects instead of opening the user-mode ones (using IoCreateNotificationObject). Anybody else experiencing this? Thanks for any help or advice.

You are probably being bitten by sessions. This is going to get worse not
better, with things like Vista/Longhorn where services run in their own
session. If you have to use events, have the application call the driver
with the handle of the event.

Try creating nameless events and pass their handles to the driver using
some IOCTL.
