You probably don't have all necessary ports open. I suggest you take the front-end server out of the DMZ and use an ISA server or other web proxy appliance in the DMZ instead of a front-end server.

Connecting to my front-end server in the DMZ, I can provide credentials to one back-end server's mailbox and OWA fires up just fine. To my test back-end server, however, I get the infamous "HTTP/1.1 503 Service Unavailable" error. I've scouted around, gone through the whole process of rechecking everything from the Front-End and Back-End Topology article, and got nowhere. Inside the network, I can type servername/exchange/username and correctly connect to the right server that hosts the mailbox every time, even if I type the wrong servername, which is expected behavior anyway. Any ideas? ==================================== Larry Wahlers, Systems Specialist 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/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe send a blank email to %%email.unsub%% Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
