ISA doesn't "load balance" in that sense. The only thing it can do is
provide a setting for the web clients to use a backup route if the primary
one fails to respond.
This setting is really only useful if the primary ISA fails to respond, not
when you lose external connectivity.
Part of the problem is that ISA isn't really "aware" of the connection
beyond its own NICs.
If you want real redundancy, you'll have to use additional hardware (no; NLB
doesn't handle external issues either), and they're pricey.

Subject: [isalist] Arrays
http://www.ISAserver.org
Hi,
I have installed two ISA servers in an Array. Both of them have 2MB ADSL
lines going into them, and all clients are running the firewall software.
I have also made a single DNS entry pointing to both servers.
What I am trying to achieve is redundancy, but the problem I get is that if
one ADSL line goes down, no one can get web services until I stop the
services on the firewall connected to that line. Then everyone fails over
perfectly
Is there a way that ISA can deal with this eventually without user
intervention, or can someone recommend me a 3rd party add on that can.
Cheers,
John Burridge
