For those with MSDN or Action Pack subscriptions, you will soon see ISA 2006 showing up on your doorsteps. A normal (?) question may be: can I install ISA 2006 on my SBS server? One answer is: "Sure, you can do anything you want." But that would not be the right answer. The right answer is: "No way, Jose!"
Why? Because you not only break your EULA agreement, but more importantly, you'll break CEICW by installing ISA 2006 on your SBS server.
However, with ISA 2006 there is a new ISA Firewall Client that works with ISA 2006, ISA 2004 and ISA 2000, and it works on both 32 and 64 bit workstations. You can download it here:
And you can find out how to distribute it to your users here:
Please note: when I tried installing the new Firewall Client, I had to uninstall the current Firewall Client first, and then make sure that Outlook and all IE windows were closed. I also had to reboot the workstations after installing the new FW Client.
