I have a TCP/IP server running on the Windows 7 machine. I call the function getaddrinfo which returns the ::0 address (IPV6_ADDR_ANY). I use the following options while calling this function: hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_flags = AI_PASSIVE; I then bind the socket to a port using this address. I also have a TCP/IP client running on Windows Server 2003 machine. When I call the getaddrinfo function on the client passing the hostname of the Windows 7 machine it returns the IPv4 address for the Windows 7 machine running the server. Now when I do a connect call from the TCP/IP client to the Windows 7 machine I get a socket error 10061 which means that the Windows 7 machine actively refused the socket connection. Any clues how to fix this ? The firewall on the Windows 7 machine is turned off. In the TCP/IP server if I bind the socket to the IPV4_ADDR_ANY(0.0.0.0) by passing AF_INET in the hints.ai_family then everything works fine.
