RPC over HTTP Issues - Front-End/Back-End (GG) Server Configuration

Hi,

I am hoping that someone will be able to assist me with a setup issue which
I am having with the setup of RPC over HTTP in a Front-End/Back-End (Global
Catalog) server configuration.

I have the following setup in place:

All servers are running Windows Server 2003 SP1 and I have Exchange Server
2003 SP1 installed on both the Front-End server and the Back-End server. I
have deployed an Ent CA on the first domain controller, which is also a
global catalog server. Both of the Exchange servers are running Enterprise
Edition.

2 x Domain Controllers

1 x Domain Controller - Global Catalog server, Ent CA
1 x Domain Controller - Global Catalog server, Exchange Server 2003 SP1
(Back-End for OWA and RPC over HTTP)

1 x Member Server

1 x Member Server - Exchange Server 2003 SP1 (Front-End for OWA and RPC over
HTTP)

I have successfully configured OWA on the Front-End server with an SSL
certificate, so SSL is in force on the Default Website on the Front-End
server and I have configured Integrated Authentication and Basic
Authentication (with the Windows 2003 domain configured as the default
domain) on both the 'RPC' and 'RPCwithCert' virtual directories, as well as
following the instructions in the following article:

So far, I have setup and MAPI profile on a client with Office 2003 SP1
installed, as well as the rest of the current updates; which is located in a
workgroup, connected to the Internet with a D-Link ADSL router. I have got
it to the point that when I attempt to logon to my mailbox, the IMAP profile
is able to contact the remote domain, as I get prompted to enter a username
and password - this I do, Outlook is then able to resolve the servername and
the mailbox name, as both are underlined but I then get informed that the
folders can not be open and Outlook then exits.

I have ensured that the correct TCP and UDP ports are open on the firewall
which sits in-front of the Exchange servers.

Is there something that I am missing? I look forward to your replies.

Many thanks,

hi there.
as long as the front-end has a certificate from the CA with proper naming,
it would be fine. edit the rpcproxy registry point to back-end and enable the
exchange proxy https at the outlook client and check the proxy server at the
IE as well and it will be running fine. the guides helps alot. :)
