Failure to receive data TDI connection endpoint. Please help

Dear experts,

I seem to be getting a STATUS_INVALID_DEVICE_STATE (status = 0xC00000184) whenever I try to receive data from connection enpoint. My code follow:

NTSTATUS Recv(PFILE_OBJECT FileObject, PVOID Data,
ULONG Length)
{
NTSTATUS status;
PIRP Irp;
PDEVICE_OBJECT DeviceObject;
PMDL Mdl;
KEVENT Event;
IO_STATUS_BLOCK IoStatus;

ASSERT( KeGetCurrentIrql() == PASSIVE_LEVEL );
KeInitializeEvent(&Event, NotificationEvent,FALSE);

DeviceObject = IoGetRelatedDeviceObject(FileObject);

Irp = TdiBuildInternalDeviceControlIrp(TDI_RECEIVE,
DeviceObject,
FileObject,
&Event, &IoStatus);

if (Irp == NULL)
{
VLSDLogS(“VLSD: Receiving data fail because of insufficient MDL resources.”);
DbgPrint(“VLSD: Receiving data fail because of insufficient MDL resources.n”);
return STATUS_INSUFFICIENT_RESOURCES;
}

Mdl = IoAllocateMdl(Data, Length, FALSE, FALSE, Irp);
if (Mdl == NULL)
{
VLSDLogS(“VLSD: Receiving data fail because of insufficient MDL resources.”);
DbgPrint(“VLSD: Receiving data fail because of insufficient MDL resources.n”);
IoFreeIrp(Irp);
return STATUS_INSUFFICIENT_RESOURCES;
}

//MmProbeAndLockPages(Mdl, KernelMode, IoModifyAccess);
__try{
MmProbeAndLockPages ( Mdl, KernelMode, IoModifyAccess );
} __except ( EXCEPTION_EXECUTE_HANDLER ) {
DbgPrint ( “VLSD: Exception at MmProbeAndLockPagesn” );
IoFreeMdl( Mdl );
Mdl = NULL;
return STATUS_INSUFFICIENT_RESOURCES;
}

TdiBuildReceive(Irp, DeviceObject, FileObject, 0, 0, Mdl, TDI_RECEIVE_NORMAL, Length);

status = IoCallDriver(DeviceObject, Irp); // Error happend here
if (status == STATUS_PENDING)
{
VLSDLogS(“VLSD: Wait a moment for receiving all data.”);
DbgPrint(“VLSD: Wait a moment for receiving all data.n”);

ASSERT( KeGetCurrentIrql() == PASSIVE_LEVEL );
status = KeWaitForSingleObject(&Event, UserRequest,
KernelMode, FALSE, 0);
if(!NT_SUCCESS(status))
{
VLSDLogSL(“VLSD: Cannot wait, time out or error 0x.”, status);
DbgPrint(“VLSD: Cannot wait, time out or error.n”);
}
}

MmUnlockPages(Mdl);
//IoFreeIrp(Irp);

DbgPrint(“VLSD: Status = %lx, IoStatus.Status = %lx, IoStatus.Information = %ld.n”,
status, IoStatus.Status, IoStatus.Information);

return status == STATUS_SUCCESS ? IoStatus.Status : status;
}

NTSTATUS EventReceive(PVOID eventContext,
CONNECTION_CONTEXT connectionContext,
ULONG Flags,
ULONG Indicated,
ULONG Available,
PULONG Taken,
PVOID tsduBuff,
PIRP *Irp)
{
DbgPrint(“VLSD: Receive Flags = %lx, ReceiveFlags = %ld, BytesAvailable = %ld.n”,
Flags, Indicated, Available);

*Taken = Available; *Irp = 0;

return STATUS_SUCCESS;
}

And server send out 2048 bytes in two times (1024 bytes/time). EventReceive debug print out:
ReceiveFlags = 0xe20, BytesIndicated = 1024, BytesAvailable = 1024.
ReceiveFlags = 0xe20, BytesIndicated = 1024, BytesAvailable = 1024.

And debug print out:
Status = 0xC00000184
IoStatus.Status = 0x2e0064
IoStatus.Information = 7274604

Anyone can help me?

Thanks in adv, VL
