I am suspicious that it is an SAP process which is rapidly opening/closing UDP ports and exhausting temporarily exhausting the network resources, but all documentation I have found refers to this problem in relation to TCP sessions, not UDP. tcp/udp contrasts tcp is stream tcp is reliable tcp is point to point and "connected" connect/accept specify addresses at setup time, read/write don't need addresses data is checksummed udp discrete packets udp is unreliable udp can broadcast, 1 to N or server can receive from many clients each read/write specifies address. And as you're always sending out updates from the server, it doesn't really matter if the odd packet or so doesn't arrive or arrives malformed. As a result, the client can't connect to it. The bulk of it was written back when mailing lists and news groups were the best ways to find people who knew Winsock deeply, and so drew heavily from those resources. In MSDN they say that the function returns the number of bytes sent, that can be less then the buffer?s length passed as a parameter in sendto().

Sockets are the foundation of all network based programming. Programs may cause the Winsock protocol to. Here is a simple procedure. A text message is transferred from server to client and then from client to server. The only difference between send() and write(2) is the presence of flags. This style of server has two big advantages over the multithreaded server : it doesn't have all the context switching overhead associated with threads, and the code is easy to port to nearly. An Overview of UDP and TCP TCP is a connection-oriented protocol layered on the top of IP of the TCP/IP stack with the ability to acknowledge receipt of packets at both ends.
