In this document:
http://support.microsoft.com/default.aspx?scid=kb;en-us;827330
Which in the link that you provide it says : Additionally, make sure
that the RPC proxy server can communicate with the back-end Exchange
2003 computers by using RPC communications. Verify that you can resolve
the name of the back-end Exchange 2003 computer from the RPC proxy
server.
How do I make sure that RPC proxy server can communicate with the
back-end Exchange?
Steps 3, 4, 5, 6, 7 (tested), 8 (didn't see port 6002 in tom's notes??),
and when I run outlook /rpcdiag all I can see if the directory and
server trying to connect and then I get a window saying "Your Microsoft
Exchange Server is unavailable." I got this message by disabling the
rpctcpfallback in the registry which forces Outlook not to fallback to
RPC over TCP/IP.
I am still at a loss.
Andrew

Hi Jim,
The client runs Office 2003 Pro, thus Outlook 2003. We are installing
SP1 as I type this message and will test it again, but can I be sure
that its related to not having SP1?
We have the client machine connected to a DSL modem in the same office
but non of the traffic goes through the server, it all goes out to over
the internet back into the office.
Thanks
Andrew

RPC/HTTP doesn't use the RPC application filter.
Any "real" RPC traffic you see is a result of client misconfiguration.
What is the client you're using (OS/SP/Office ver / patches)?
Where is the client operating from; internal or external to ISA?

Subject: RPC over HTTP problems
Hi,
I have setup RPC over HTTP along with OWA using Tom's Exchange / ISA
info. Though I don't think there is any problem with his material I am
having a problem wirh RPC. The OWA with SSL works flawlessly.
When I setup the log in ISA to only look at the machine that we are
using on the external side to connect to RPC over HTTP its able to
negoicate with HTTPS on 443 without any problems but the RPC (all
interfaces) id denied access by the default rule. I am wondering is
there something else I need to set on ISA to enable the RPC protocol to
work?
Thanks
Andrew
