If you have only one Exchange back-end server, then that could well be a fine idea. One advantage to a front-end server or a network-load-balanced team of them is that you can have a single URL for all users that won't redirect to the proper back-end server. That makes firewall mapping easier.

Use FE Servers for protocol load balancing and put them inside with the Exchange Servers. Use ISA to publish Exchange resources for controlled access from outside. This architecture involves much more than Exchange. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pillai, Raj Sent: Wednesday, February 05, 2003 2:49 PM To: Exchange Discussions Subject: RE: Front end Server OK, Any one using an ISA Server in the DMZ connecting to an Exchange Server through the firewall? I have been looking at some technet articles about a "trihomed ISA Server in the Perimeter network". Is this a better option? Thanks for all the ideas.

FE Exchange Servers are not security devices, contrary to what you may have been told. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pillai, Raj Sent: Wednesday, February 05, 2003 11:05 AM To: Exchange Discussions Subject: RE: Front end Server To keep the BE server secure ( do not want to open the OWA ports to users who are not using VPN and dialup). Also we have a document management software (imanage) which could be integrated to Outlook. Since the users access the Imanage web portal via the web, they could access their email also via owa (secured with SSL). Any other suggestions would be welcome.

An IBM workstation class machine with Pentium 4, 1.80GHz CPU with a 36GB HDD is being used for this purpose. I am not expecting more that 20-25 concurrent connections to this box at any given time. Will this box be able to handle this load or do I need a "Server class" machine? Exchange 2000 enterprise sp3, windows 2000 server sp As always I appreciate all your input.
