SID (2 bytes): This field MUST be the search identifier (SID) returned in TRANS2_FIND_FIRST2 response.

SearchCount (2 bytes): This field MUST be the maximum number of entries to return in the response.

InformationLevel (2 bytes): This field contains an information level code, which determines the information contained in the response. The list of valid information level codes is specified in section 2.2.2.3.1. A client that has not negotiated long names support MUST request only SMB_INFO_STANDARD. If a client that has not negotiated long names support requests an InformationLevel other than SMB_INFO_STANDARD, the server MUST return a status of STATUS_INVALID_PARAMETER (ERRDOS/ERRinvalidparam).

ResumeKey (4 bytes): This field MUST be the value of a ResumeKey field returned in the response from a TRANS2_FIND_FIRST2 or TRANS2_FIND_NEXT2 that is part of the same search (same SID).

Flags (2 bytes): This bit mask field is used to request that the server manage the state of the transaction based on how the client attempts to traverse the results.
