Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

This update causes ISA Server to use random source ports for UDP sessions created by access rules which serve hosts in networks for which ISA Server defines a network address translation (NAT) relationship.

• 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).
