RE: Outlook clinet config for RPC/HTTP



I'm starting to figure this stuff out. I can get it all to work form the
Internet as long as my Proxy referances the DNS name.
Does the Proxy URL have to point to a DNS name? can it point to just an IP
address?

This is very much normal.
You should try to access using outlook.

RPC OVER http
Behind ISA everything works but in testing and trying to tag the
rpc/rpcproxy.dll from the Internet I get a “403” Access denied error.
I have looked at the ISA logs, the RPC Proxy server logs (front-end server)
and I’m not seeing any security “logon failures”
If everything is working behind ISA, and all I am changing going from inside
to outside ISA is the RPC Proxy address, I would think that the problem would
be at the ISA server, is this sound thinking?
If this is the case what is the most common cause for this “403” error?

Yes off coure you have to place the certificate on ISA server and you have to
use that certificate in the https listener in ISA.

Some of my questions may be a no brainer to some bear with me please
Does the certificate on the RPC Proxy also have to reside on the ISA server,
or is this passed thru from Proxy to client?

When publishing the internal RPC Proxy on the ISA does “/rpc” folder also get
Published? Also is it just “/rpc” or “/rpc/*”
In the past when publishing an internal server with a folder the focus from
the out side would be the external DNS or IP along with the folder.
Example; mail .xxx.xxx/exchange

In the Outlook client, when referencing the RPC Proxy it has not allowed me
to add the folder "/rpc" reference, it has allowed the server name only.
So when setting up the ISA publishing rule and the path’s I guess I have to
associate just the public name or IP (which the Out look client RPC Proxy
will be pointing at)with the internal RPC Proxy server which will also have
it’s “/rpc” folder added to the publishng rule

Does any of what I‘ve tried to explain make any since

Name of the exhange server will remain the same, but the URL https:// will be
pointing towards the ip of the external interface of ISA server and you will
use ISA server publishing to publish your internal RPC proxy server.

RPC over HTTP; I have my Outlook clients working behind my ISA server on the
intranet. Now to take an Outlook client from behind ISA and move them out to
the Internet, I need some help in configuring the client.

It seems that my Exchange server reference would have to change from an
internal reference to a legitimate Internet private IP reference, correct?
This could be a real pain for those guys that I and out of the office
In the “Exchange Proxy Settings” does the HTTPS:// also point to my
legitimate Internet IP address (ISA server) or does it point to my internal
RPC Proxy server?
