Socket error 10052 on UDP socket
sockets
Solution
See http://msdn.microsoft.com/en-us/library/ms740120%28v=vs.85%29.aspx, which describes the recvfrom function. It says of WSAENETRESET (which is winsock error 10052):
For a datagram socket, this error indicates that the time to live has expired.
Problem
We have a .NET 2.0 desktop application which sends and receives network packets over UDP. Several users have reported an occasional socket error 10052 which happens when the code calls socket.BeginReceiveFrom on a the UDP socket. What does this mean? The official MS documentation for socket error 10052 says - quote: "WSAENETRESET (10052) Network dropped connection on reset . The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed." This just doesn't make much sense for a UDP socket since UDP is a connectionless protocol. I know that another close error code 10054 in connection with UDP sockets means that an ICMP message "Port Unreachable" was received, and I am wondering if 10052 might map to another ICMP message? I have googled this for months, read network books, etc. but can't find anything. Please help - what does socket error 10052 on a UDP socket mean? Thanks in advance
