Armando,
You have two choices. If you have an intermediate router, assign both
ISAs as the default gateway. Then have your clients point their default
gateway to the intermediate router. This works using a concept called
Dead Gateway Detection. If one gateway fails, the router will
automatically switch over to the next default gateway on the list.
This also works if you assign two gateways on the client end. However,
each client will switch over individually when it detects a dead
gateway.
My recommendation is to use the first option. It's much cleaner and
does not require modifying the client desktop other than changing the
default gateway to point to an intermediate router.

http://www.ISAserver.org
Hi, I have 2 ISA's installed in my network, but only one is giving the
service. It's named ISA1, the other ISA2.
I have all Web Proxy, Firewall and SNAT clients using ISA1.
The ISA2 is only for backup and tests.
Both servers are installed as standalone because we don't have active
directory.
Is there a form to quickly change all my clients so that they start
using
ISA2 in the case that ISA1 stops working?
Of course what i don't want to do is changing in all the clients the
name
from ISA1 to ISA2.
Any ideas?
Thanks.
