Changing the socket address causes some applications to attempt to bind the same port twice. These applications enumerate all adapters on the local machine and bind to their unique addresses so they can receive UDP broadcast messages on every connected network.
By default, binding to 0.0.0.0:<port> will only bind to the primary adapter of the machine using Windows. --- dlls/ws2_32/socket.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
