It seems that Vista implements RFC 3484 address selection, including the requirement to sort IP addresses. This breaks a great deal of operational dependence on DNS-based load balancing, as well as being based on an incorrect understanding of how IP addresses are allocated. RFC 3484 needs to be updated to delete this rule, so that the order returned from the DNS is honoured when the client has no better knowledge about which address is appropriate.
