FsRtlRegisterUncProvider problem

NTFSD
1

Hi,

I am writing a FSD network redirector. I am calling
FsRtlRegisterUncProvider() to get registered with MUP. It fails out giving
status as 0xC0000103. Probably because of this problem while registering, I
am facing too many problems with Office applications using the redirector.
Is there anything that I am missing out? Please help.

Regards,
Ram

Status = IoCreateDevice(DriverObject, sizeof(IBFS_EXT), &DeviceName, FILE_DEVICE_NETWORK_FILE_SYSTEM, 0, FALSE, &DeviceObject );Status = IoCreateSymbolicLink(&DosDeviceName, &DeviceName);IoRegisterFileSystem(DeviceObject);Status = FsRtlRegisterUncProvider(&MUPHANDLE, &DeviceName, FALSE);

At least in NT4 this function could be called from a System process
only. Use a work item to call it.

I call it within DriverEntry for NT/Win2k. Never gave me any problem.

DriverEntry is called in the context of the system process. Thus, your driver wouldn’t encounter the bug Maxim disclosed.

Yes, this bug occurs when FsRtlRegisterUncProvider is called from the
IOCTL path in something like IOCTL_START_REDIR functionality.
