If the server succeeds in opening a durable handle to a file as requested by the client via the SMB2_CREATE_DURABLE_HANDLE_REQUEST , it MUST send an SMB2 CREATE_DURABLE_HANDLE_RESPONSE back to the client to inform the client that the handle is durable.If the server does not mark it for durable operation or the server does not implement durable handles, then it MUST ignore this request.
