3.2.5.1.3 Receiving any Batched ("AndX") Response
When a client receives an AndX Response, the client MUST process the batched responses sequentially. Each individual response is processed as specified in its respective Message Processing subsection.
The client MUST use the information in the AndX Response header as the header information for each response, with the exception of the SMB_Header.Status field. The status field indicates only the error status of the last response in the chain. All other responses in the chain MUST be interpreted as having completed successfully. If processing a response in the AndX Chain causes a change in state that would affect the information in the header, the updated header information MUST be used when the client processes the subsequent response in the chain.
