在win7中无法打开TDI连接

/*

&usTdiDriverNameString,
OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,
NULL,
NULL);

/*

*/
RtlCopyMemory(&pExtendedAttributesInformation->EaName, TdiConnectionContext, TDI_CONNECTION_CONTEXT_LENGTH);

pExtendedAttributesInformation->EaNameLength = TDI_CONNECTION_CONTEXT_LENGTH;
pExtendedAttributesInformation->EaValueLength = TDI_CONNECTION_CONTEXT_LENGTH;
/* Must be at least TDI_CONNECTION_CONTEXT_LENGTH */

dwEASize = sizeof(DataBlob);

NtStatus = ZWCreateFile(pTdiHandle,
FILE_READ_EA | FILE_WRITE_EA,
&oaTdiDriverNameAttributes,
&IoStatusBlock,
NULL,//0,
FILE_ATTRIBUTE_NORMAL,
0,
FILE_OPEN_IF,
0,
pExtendedAttributesInformation,
dwEASize
);

if (!NT_SUCCESS(NtStatus))
{
DebugPrint(("ZwCreateFile failed with status %x\n", NtStatus));
return NtStatus;
}

if(NT_SUCCESS(NtStatus))
{
NtStatus = ObReferenceObjectByHandle(*pTdiHandle,
GENERIC_READ | GENERIC_WRITE,
NULL, KernelMode,
(PVOID *)pFileObject, NULL);

DebugPrint(("TdiFuncs_OpenConnection ObReferenceObjectByHandle %x\n", NtStatus));

if(!NT_SUCCESS(NtStatus))
{
ZwClose(*pTdiHandle);
}
}

return NtStatus;
}

在winxp中ZWCreateFile这个函数返回成功
而在win7中,ZWCreateFile返回c000000d,即:无效参数

Win7下是WFP，TDI废弃了。

请问可以将TDI驱动改为WPF驱动吗？ 如果可以请问要注意哪些地方.。。小弟刚接触驱动这块，不是很懂，希望能讲详细点...谢了！！！
