ISA Server (Internet Security and Acceleration Server) is gone … now we are talking TMG (Threat Management Gateway)
Microsoft announced last week in RSA about the new Threat Management Gateway (TMG). Now you can download a BETA version of the product, but you will need 64BIT machine with Windows 2008
I recommend you reading the following TechNet documentation before running and installing TMG
