Did you do what I suggested to you on Friday? Go ask in the forums at

'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.

Subject: [exchangelist] Mail Server Name

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

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

Must Outlook clients (RPC over HTTPS) really have the name of Back-End
Exchange as mail server?

Please only solution tips and information. Thanks.

Best Regards
