MaxBufferSize

TID

MaxBufferSize (2 bytes): The maximum size, in bytes, of the largest SMB message that the server can receive. This is the size of the largest SMB message that the client can send to the server. SMB message size includes the size of the SMB Header (section 2.2.3.1), parameter, and data blocks. This size MUST NOT include any transport-layer framing or other transport-layer data.

TID (2 bytes): The newly generated Tree ID, used in subsequent CIFS client requests to refer to a resource relative to the SMB_Data.Bytes.Path specified in the request. Most access to the server requires a valid TID, whether the resource is password protected or not. The value 0xFFFF is reserved; the server MUST NOT return a TID value of 0xFFFF.
