Someone else is using the same name. Try changing the name. Or perhaps
you loaded the driver, then recompiled it and tried to load it again?
No matter, if there is a name collision, us an object manager name
walking tool (there is one on www.osronline.com) to confirm this. If
you use the kernel debugger, you can walk through and find the driver
that owns the device object (or follow the sym link if it is a symbolic
link).

Subject: [ntfsd] examples from IFS kit
Hello all,
I’m newbie to driver development. I compiled examples from IFS (for XP)
(filespy and sfilter) but sfilter don’t start at all and installation
didn’t
pass (the script freezed)
Filespy installed but in DriverEntry
IoCreateDevice( DriverObject,
0,
&nameString,
FILE_DEVICE_DISK_FILE_SYSTEM,
FILE_DEVICE_SECURE_OPEN,
FALSE,
&gControlDeviceObject);
failes with the error code c0000035. As I understand this code means
that “Object Name already exists”
I have WinXP and debugged the driver with SoftIce
Did I do something wrong? Can anybody help?
