Andrew,
Have you been anywhere close to any of the articles you've been pointed
to?
You keep trying to shotgun this process and you absolutely cannot do
that.
Fact: if ISA isn't doing what you think you told it to, then you
probably messed it up somewhere. This is a standard Exch deployment and
IF you follow the instructions written by half-a-dozen knowledgeable
folks, you can get there.
Q1 - what have you used to validate that RPC/HTTP is functional inside?
By default, OL2K3 will use HTTP ONLY as a fallback protocol to contact
the Exch server
Q2 - what are the OL2K3 settings you've used to connect to the RPC
proxy?

I have basically pin pointed the issue down to ISA and the rule I think.
The PRC proxy works internally. And HTTPS works flawlessly but for some
reason the traffic is getting hung at ISA Server. When I monitor the
logs all I see now is HTTPS 443 coming in but nothing happens from that
point on wards. Except that Outlook is unavailable to find the Exchange
Server...
Shurg
Oh and Outlook /rpcdiag shows outlook trying to connect to Directory,
and exchange.domainname.com then both attempts vanish and the error
message about not being able to find Exchange Server appears.

I saw it the first time.
How the site resolves on the Internet has absolutely no bearing on how
it resolves internally.
Oranges and roadapples...

Hi Jim,
My last message didn't show up on this thread, wonder why. So here goes
again.
These people had there server setup as their domainname.local initially,
and use their owa.domainname.com for OWA, email ,etc. I recall that
there can be issues when using .local as suppose to .com especially when
doing RPC over HTTP. Do you have any ideas on what I should do other
than rebuilding their entire network? :-)
Thanks
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
