Alex,
What are your settings for the Firewall Client and Web Browser when you
look at them from the ISA Management Console?

I'm using the firewall client on all of my client
machines and we also use ISP provided POP3 from the internet.
Everything works like a charm. My opinion, which may be different than
the list, is not to have all clients secure nat to the ISA. All of my
clients have a default gateway set to my cisco router.
If you have more than one physical location that is tied
into your network, making the clients secure nat to the ISA is BS and
will cause headaches. If you do this then you're left with using the
ISA as a router for intra office communication.
My philosphy is this, clients behind the inside (south)
nic in the ISA should have the FW client installed or their web browsers
manually pointed to the IS,. and their default gateways pointed to a
cisco router. Servers that are published through the ISA should only be
your only secure nat clients, especially in in a DMZ setting.

Is it really preferable to make all internal
clients SecureNAT instead of using the firewall client? It would seem
that a Windows 2000 box would be a greater point of failure than a Cisco
router. Ours has been down twice now. Once as they fan went bad on the
Compaq DL 360 and once as the power went out on that UPS. In both cases
the Exchange servers that we publish use the ISA server as SecureNAT and
the entire company was shut off from mail. If the ISA server is the def
gateway then if it goes down not much will get done by ALL internal
clients, right? Is this the list view of a best practice (all internal
SecureNAT)? I am just curious as to the thinking.

First, if you use the firewall client to this
purpose, uninstall it.
All client machine should be SecureNAT Clients
(Default gateway should be internal IP address of ISA Server)
create a protocol rule called (for example)
allow Outlook Express, select smtp and pop3 protocol and appy to
IP addresses of these computers.
Create a site and content rule with the
destinations of mail servers....
Hope this Help,
ALEX
