Re: Trying to get RPC over HTTP for Outlook working

Interesting. What kind of certificate are you using on the ISA box?
(wildcard, san, .etc)

thanks for your reply, it puzzeles me that the current setup has been
working well with Outlook 2003 but not Outlook 2007...

ISA2004 adds a layer of complexity, but

Neo,

I have a similar situation, my domain is company.local, server name is
exchange

with respect to your suggestion to change ValidPorts entry:

at the moment I have:

exchange:6001-6002;exchange.company.local:6001-6002;exchange:6004;exchange.company.local:6004

do I need to change the above entry?

the outlook 2007 (installed in Windows XP SP2) rpc-over-http only works
outside the network only if it VPN in (we use ISA2004 here)

thanks,
Evans

You should be asking this question over in one of the
microsoft.public.exchange support groups. Also, you will need to
clarify your post a bit. Based on the below, I would assume that you
have a single Exchange server setup. If my understanding is right, you
high level checks would be...

1) Ensure that the RPC proxy component is installed on your Windows
2003 (SP1/SP2)/Exchange 2003 SP2 server

2) Enable the Exchange server as an RPC/HTTPS backend server. (Exchange
System Manager > Right click on server object > Properties > RPC-HTTP
tab) You may have to add the necessary registry keys to get this
working. Location in registry is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\RpcProxy

The DWORD value Enabled should be set to 1
The REG_SZ value ValidPorts would be set to
ServerNETBIOSName:6001-6002;ServerNETBIOSName:6004;ServerFQDNName:6001-6002;ServerFQDNName:6004

To explain the ValidPort line better, assume that the name of the
Exchange server is EXCH01 and the domain name I'm working with is
contoso.com. The ValidPorts entry would be:

exch01:6001-6002;exch01:6004;exch01.contoso.com:6001-6002;exch01.contoso.com:6004


3) I would test the connection on the internal network before testing
from the internet.

Other than that, test with SSL enabled and if you are using a private
(internal) certificates to secure the web/rpc proxy services, make sure
that a copy of the signing certificate authority is installed on the
workstations. The client operating system (assuming Windows XP SP2 or
newer) will verify the SSL certificate back to the issuing certificate
authority.

having trouble seeing my exchange server via outlook 2007 over the
internet
connecting to my Exchange Enterprise Server 2003. Have followed
Microsoft
instructions, testing first without use of of SSL certificates. I may
be a
bit confused about front end and backend servers. I have one PC, a
domain
controller at our office, a seperate PC with Exchange Only on it,
connecting
to the Domain Controller, and another PC with Blackberry Enterprise
installed. The purpose of this is to get away from use of the VPN
connection required to be part of the local network for Exchange User
access
off property. Sounds good configuring settings into the Outlook only
and
preventing other local access this way. Any ideas? Again, cannot get
the
Outlook to see the Exchange Server during the logon name and password
to
server process.
