Because I found you problem a bit interesting I decided to set up RPC over HTTP in a test environment with one W2k3DC/GC and one
Exchange Server 2003SP1 installed on a Member Server.

This is how I got RPC over HTTP(S) to work:

Installed a CA Enterprise on my GC
Installed RCP over HTTP on the Exchange Server
Added a certificate on the Default Web Site with the common name ExchangeserverFQDN
Removed Anonymous Access and added Basic Authentication on the RPC Virtual Directory

In registry on my ExchangeServer I modified the key ValidPort under HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\RpcProxy\ with the
following value

ExchangeserverNetBIOS:593;ExchangeserverFQDN:593;ExchangeserverNetBIOS:6001-6002;ExchangeserverFQDN:6001-6002;ExchangeserverNetBIOS:
6004;ExchangeserverFQDN:6004;GCNetBIOS:593;GCFQDN:593;GCNetBIOS:6004;GCFQDN:6004

In the registry on my GC I added a Multi-String Value with the name "NSPI interface protocol sequences" and value ncacn_http:6004
under the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters

For the proxy authentication settings in my Outlook Profile I used Basic Authentication.

You haven't added the settings for your GC in the key validport and that may be the reason for the problems you are having. Hope
this will help.
