Hi list, I have a hardware firewall, on the DMZ of this firewall there is an ISA2004 which is connected to the DMZ and the Internal network, in the internal network there is a front end exchange and back end exchange, publishing the front end exchange OWA is done currently through the hardware firewall directly. We want to publish the OWA with a secure certificate through the ISA, where do I make the .scr file request? On the exchange front end server or the backend server? Note: The mail record for the OWA at the ISP will point to a public IP which will be added as a second IP for the DMZ interface of the ISA2004. thanks r.c.
