It seems that I have missed this one when it popped up. However it is still not too late to start testing Internet Security and Acceleration (ISA) Server 2006 Beta and to evaluate this new upcoming version.
Download and try the latest Beta version of the firewall, VPN, and web cache solution and learn more about how you can protect your IT environment from Internet-based threats while providing your users with secure, anytime, anywhere access to Microsoft applications and data.
