        This update resolves the issue described in Microsoft Article 956910,DNS queries that are sent across a firewall do not use random source ports after you install security update 953230 (MS08-037). With this update, ISA Server allocates a large set of random UDP ports and then selects a port from this set for use in new UDP sessions.

        You can disable it programmatically (there is no user interface).
