There are several issues that you’ll need to consider when upgrading to Windows Server 2003 SP2 on devices running the ISA Firewall. Make sure that you review these issues pointed out on the ISA Server Team blog at https://blogs.technet.com/isablog/archive/2007/03/27/isa-server-and-windows-server-2003-service-pack-2.aspx before making the upgrade.
