The FIND_NAME_HEADER structure contains information about a network name. This structure is followed by as many FIND_NAME_BUFFER structures as are required to describe the name.
typedef struct _FIND_NAME_HEADER { // fnh 
    WORD  node_count; 
    UCHAR reserved; 
    UCHAR unique_group; 
} FIND_NAME_HEADER; 
 The FIND_NAME_HEADER structure is pointed to by the ncb_buffer member of the NCB structure when an application issues an NCBFINDNAME command.
