I need to create the key on my exchange server to allow me to use specified ports for rpc over http. The key contains the following entry

ExchangeServer:6001-6002;ExchangeServerFQDN:6001-6002;ExchangeServer:6004;ExchangeServerFQDN:6004;

where

ExchangeServer is the NetBIOS name of your Exchange server.

ExchangeServerFQDN is the fully qualified domain name (FQDN) of your Exchange server.

I access my outlook web mail at mail.website.co.uk\exchange from external PCs. My exchange server is called ex2k and is on internal domain intdomain.local, and the isa server isa2k is a member of this domain.

What is the fqdn and netbios names given the above details?

Thanks

Hi BCR999,

The NetBIOS name is EX2K and the FQDN is EX2K.INTDOMAIN.LOCAL (FQDN of the server from the internal network).

Hi Henrik

Thanks for the reply. How do external clients on the internet, not the internal network, resolve ex2k.intdomain.local. At the moment they resolve mail.website.co.uk to the external card on the isa server. When I create an outlook profile on the external client what will be the outlook settings for connecting to exchange using http.

Thanks

The RPC traffic travels over HTTP(S) to the RPC Proxy server which resolves the internal names (by contacting the GC).

In the Outlook profile you should as the Exchange server name specify the internal FQDN of the Exchange server and in the Proxy settings you should use the external FQDN.

Hope this helps!

I can now get the outlook client to connect via HTTP to exchange on the internal network, but I am unable to get it to work from external clients.

The internal clients work with exchange server set to ex2k.intdomain.local, and the connect to exchange using http settings are set to mail.website.co.uk as the url and the msstd principal name. The authentication is set to basic.

I can then connect with entering intdomain\username and the user's password.

I have used the same settings on external internet clients, but cannot get them to work. The external client get the correct rpc page (read access denied) when connecting to mail.website.co.uk\rpc, but outlook gets stuck on a logon prompt

What do you think I am doing wrong.

Where should the RPC server be installed - on the exchange server or on the isa server (just to clarify).

Thanks

If you use a self-issued certificate you must make sure the external clients trust it. Said in another it needs to be installed into the trusted root certification authorities store in IE.

I have installed the certificates into the personal and trusted authorities store for current user and local computer, but still not working from external client.

When this client is on the internal network, it connects ok over http.

When removed from internal network and attempting to connect over internet it fails. The same certificates are still present in the same places. I'm sure it cannot resolve the internal exchange name ex2k.intdomain.local when on the internet.

Outlook gives me the message (0x8004011D) The server is not available.

Any ideas?
