Hi all Happy new year...

I have some question Plz... help me...

I was Developed Network IM Driver in Windows2000. It works well....

And I handle that driver for 'CreateFile' and 'DeviceIoControl'... It works well too...

BUT,

when I was close it, That Occur Page fault in 'CloseHandle' ( In App )function. It cann't reach at "IRP_MJ_CLOSE" hadle function.

and cann't reach Unload handle..

I don't understand why ...... Do you have any Idea? and.. What can I do....?

Thank you all before....

Have nice day....

Did you register an Unload function in DriverEntry? In that Unload did you
unwind all resource usage, in precise reverse order of acquisition, and
release all device objects?
