Of course running OWA in a FE/BE setup with OWA in the DMZ is ideal. Then the advantages of ISA are diminished.
However, for smaller organizations who wish to run OWA, ISA can act as the intermediary and only allow pre-authenticated connections into the OWA server. ISA pay's for itself by eliminating the need for a FE Exchange server while achieving _close_ to the same level of security.

We're running a plain ol' Exchange 2003 Front End Server in our DMZ to do both OWA and RPC over HTTP(s). Our smart host is PMDF on VMS/ALPHA with SOPHOS for virus scanning, PMAS for anti-spam, and vFastScan to speed up the scanning - it loads all the virus defs in memory. And, no, I don't work for or get kickbacks from or even know anybody personally who works for any of the above companies! -- Larry Wahlers Concordia Technologies The Lutheran Church - Missouri Synod _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
