Did you do what I suggested to you on Friday? Go ask in the forums at isaserver.org? 'Cuz if they can't tell you, I doubt very highly that anyone here can. This is an ISA question, not really an Exchange question. -----Original Message----- From: Mustafa Cicek [mailto:mbcicek@xxxxxxxxx] Sent: Monday, October 18, 2004 8:33 AM To: [ExchangeList] Subject: [exchangelist] Mail Server Name http://www.MSExchange.org/ Hi! I have the following network: Internet >> NetscreenFirewall_1 >> ISA 2004 >> NetscreenFirewall_2 >> Internal Network with two Exchange 2003 FE and BE servers and one global catalog. The external clients can access Exchange over OWA/POP3/IMAP4/SMPT without any problem. The same clients can access Exchange 2003 by using RPC over HTTPS only when they have the name of Back-End Exchange name as mail server name on Outlook client. Back-End Exchange name is NOT published by using ISA. Only FE is published. Also the external DNS server has NO RECORD for Back-End Exchange server. Why can the external Outlook client resolve the name of Back-End Exchange successfully? I do not want that the external clients have the name of Back-End EXchange. They should know only the name or IP of ISA Server. Must Outlook clients (RPC over HTTPS) really have the name of Back-End Exchange as mail server? Please only solution tips and information. Thanks.
