This describes perfectly what a Winsock reset performs and it doesn't exactly correlate with your FUD: http://support.microsoft.com/kb/299357 http://support.microsoft.com/kb/299357 So there is no real distinction here between a Winsock reset and the equivalent operations in the other 2 big OSes. The difference is that whilst Windows holds its network configuration in the Registry (ugh), the other two do not. The operations being performed is otherwise pretty much identical.
