In a LAN,the servers are using Netware,and workstations are using Dosˇ˘Win98ˇ˘WinNt or Win2000.They are all setuped with IPX/SPX protocol.The servers bind Ethernet 802.2 and Ehternet 802.3 or others to assign multi-network .
I wrote a program using IPX Protocol in the LAN refered above.The program includes two section.One Boardcasts some data.
Another receives these data.The problem is some workstations receive repetitive packets , some receive no packets , some
lost several packets,and others are right.
In the sending program I defined:
typedef struct IPXAddress
unsigned char net[4];
unsigned char node_address_type[6];
unsigned short socket;
typedef struct IPXHead
unsigned short checksum; // = 0xffff;
unsigned short length;
unsigned char transport_contol;
unsigned char packet_type; //= 0x04
unsigned char dest_net[4]; //Accordint to actual condition , assigned the network address.
unsigned char dest_node[6]; //Assigned 0xff,0xff,0xff,0xff,0xff,0xff
unsigned short dest_socket; //Assigned destination corresponding socket.
unsigned char source_net[4]; //Accordint to actual condition , assigned the source network address.
unsigned char source_node[6]; //Assigned source node address.
unsigned short source_socket; //Assigned source corresponding socket.
typedef struct ECB
unsigned short link[2];
unsigned long ESR;
unsigned char in_use;
unsigned char complete;
unsigned short socket;
unsigned char IPX_work[4];
unsigned char D_work[12];
unsigned char immediate_address[6]; //using IPX_GetLocalAddress() To getting the immediate address.
unsigned short fragment_count;
unsigned long fragment_data;
unsigned short fragment_size;

Workstations specified ipx/spx frame type to be auto, and received many repeative packets.Sometimes workstations specified ipx/spx frame type to be Ethernet 802.3 and works well.But in general , Users hope that the workstations specified to be auto .How to modify my program.
Thank you! Good Luck!
