Comments

• The Windows Vista issue we encountered has to do with how
  Vista reacts when a new process attempts to bind to a port
  in use by an existing process running on the same host.
  Windows XP and Vista SP2 throw an error that the port number
  is in use, forcing our software to choose a new port. We
  then try the next port and, if available, we bind to that
  port and use it to communicate with the server process
  (local or remote). With the unpatched Vista client, when we
  try to bind to an existing port, we still get the error that
  the port is in use, but when we try to bind to a different
  port, Vista reports the "Invalid argument" error and appears
  to trash the socket we had initially opened for the bind (no
  socket operations are possible any longer after the first
  bind failure). This appears to have been fixed by Vista
  Service Pack 2.
