Tom and Jim,
Thank you very much for your replies. This definitely helps me. Is ISA
2000/Exchange Kit downloadable from Microsoft site? Is it part of the
Feature Pack 1 ?

Thanks. 


Regards,
Raj

Hey guys,

In this OWA and RPC/HTTP scenario, delegation of basic auth should work
fine, as long as SSL to SSL bridging is used. So, unless the users are
fans of double authentication prompts, this should work.

The huge, monstrous, fearfully nasty stumbling block you have to
overcome is whether or not you expect ISA to authenticate those
requests.
If not, then you're golden.
If you do, then you have to ask yourself if you're willing to fire a
shotgun into the face of your internal "firewall" to allow AD-membership
traffic through.

Hello List,
We are in process of designing our OWA and RPC over HTTP deployment. We
would like to use ISA server in the DMZ as reverse proxy. However, we
currently have a DMZ with two third party firewalls, one external
firewall and one internal firewall. We want to integrate ISA 2000 server
between these two firewalls, and authenticate users to the front-end
Exchange 2003 server that will be located behind the internal firewall
in the corporate network. Microsoft documents indicate ISA 2000 server
needs to be installed in firewall mode with two network interface cards
for this scenario. This is not suiting our current network, since we
want the ISA server to be located in the DMZ between the existing
firewalls. I was reading an article by Tom Shinder about "ISA Server
2000 Application Layer Filtering Web Proxy in the Perimeter Network".
This document is very brief, I think I need buy the Tom Shinder book for
the complete document (..which I will). However, could some one please
let me know, If the ISA server is located in the DMZ between the
existing firewalls as an application layer filtering web proxy, can it
provide the full functionality for OWA and RPC over HTTP publishing ?

Thank you in advance.

Regards
Raj
