Praveen,
When you configure an Outlook profile, the Outlook always tries to
connect to Exchange server using RPC to resolve the user name. Hence if
you are trying to create a profile from outside of a DMZ, your profile
creation will give errors since the RPC protocol is blocked. Yes, you
need to have RPC protocol enabled between your FE and BE servers. When
you create the Outlook profile, your Exchange server name should be the
BE server name, not the FE server name. If you use the FE server name,
Outlook will not recognize your user name and Exchange server name. If
you are trying to create the profile from outside the DMZ, then you have
click OK ..OK as the error messages pop up about un resolvable name. But
make sure the exchange server name you put in is the BE server name not
the FE. Once the profile creation ends, you can verify the profile
settings again. Although the names are not resolved, the profile should
be pointing to the BE server, and your RPC/HTTP settings should be
pointing to the FE server, which I believe is also your RPC proxy. Then,
you can open Outlook normally, if every thing is configured correctly in
your FE server, then your Outlook NOW RESOLVE YOUR USERNAME. Your
Outlook should work normally.
Another suggestion, its not a good idea or good practice to place the FE
server in the DMZ. By doing this, you are bringing the presence of your
corporate domain to the DMZ. Its always best to leave the FE server in
the corporate domain, and use an ISA server in the DMZ to publish OWA
and RPCoHTTP.
HTH.

Subject: [exchangelist] RPC over HTTP unable to configure the
client--Please help

Hi,
I am trying to setup RPC over HTTP. My FE server is in DMZ and BE server
in internal network. I have followed the procedure in Microsoft RPC over
HTTP deployment guide. I am facing problem while configuring mail
profile.
I am using Exchange 2003 With SP1 on Windows 2003 server.
1. From PC located in internal net work I tried to configure the
profile. When I try to do "check name" it keeps asking for username and
password and nothing happens
2. Tried to configure profile on PC in DMZ and it doesn't resolve
my account name and it doesn't even prompt for user name and password
OWA access through FE is working fine and MAPI access to BE is also
fine. Additionally I have allowed ports 6001, 6002 & 6004 from FE to BE.
In fact I can see traffic on these ports from FE to BE on firewall log
(Firewall Rules is applied on internal IP of FE and BE).
In understand that I should have RPC 135 open from the client PC to FE
server for me to configure the profile. I am trying to give the FE's
FQDN as server name which resolves to my FE public IP. I am following
the document in exchange.org to configure the client.
Should I allow RPC 135 to my FE external IP from my PC in internal
network??
What is that I am missing ??
Please help.
Regards
Praveen R
