Opening the driver

[bk]

Hi, what’s the correct sequence to open the NDISRD driver and close it when finished using? At the moment my sequence is:

1) Get the file and device pointers using IoGetDeviceObjectPointer()
2) I get a reference on the device object with ObReferenceObject() since I use it.
3) I dereference the file object since i don’t need it with ObDereferenceObject()

4) I use the deviceObject..

5) When finished using, i dereference the deviceObject using ObDereferenceObject()

The problem is that I can open the device only one time. The second time I try the same sequence, I can’t open the device.
