Tom, Praveen,
Not practical in many of the situations where RPC/HTTP is attractive.
Home systems, borrowed equipment when guesting away from base etc.

Raj thanks for the response.
If I give BE as server name and FE as proxy server then following thing
happens:
Client connected on same network as BE will work, but when I check the
traffic from client to server, it is still TCP instead of HTTPS. And on
server I checked with exchange monitor and it shows the client is connecting
from NATed public IP address.
Hope I am clear..
Can you please let me know what ports need to be open between FE to BE and
from client to FE, BE, ADS for me to configure this profile.
My users sit in different building and connect to this server via internet.
That is the reason I wanted to give them this solution. But if they have to
be connected to BE directly for configuring the profile then it will be
difficult. Please suggest me the best method to rollout this solution.

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.

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
