Quick, what single ISA firewall feature is most likely to boggle your mind? CARP? Access Rules? Web Listeners? Secondary Connections? The HTTP Security Filter? No, I don't think so. From my experience with the ISA firewall, 9 out of 10 ISA firewall admins have their minds boggled by NLB.
And what boggles the mind of the 1 out of 10 ISA firewall admins who aren't boggled by NLB? Its getting the new support for multicast NLB to work with the ISA firewall array.
Jason Jones comes to the aid of both the boggled and unboggled by giving a nice, clear step by step guide on how to configure multicast NLB on the 2006 ISA firewall array after SP1 is installed. Check it out at http://blog.msfirewall.org.uk/2008/08/enabling-nlb-multicast-mode-on-isa.html
