Monowall Firewall In place with an internal network of 192.168.x.x address scheme
Ports 443 and 80 Forwarded to the Exchange Server for OWA and RPC
Exchange Server 2003 Running SP2
Windows 2003 Server R2 SP2 running on both DC and Exchange
RPC Over HTTP installed on the exchange server only
I used to have a setup of a single Exchange 2003 and Server 2003 DC all on one box doing RPC over HTTPS and it seemingly worked fine for months. Since then i have added a new server and completely re-configured the network to be a seperate domain controller and seperate Exchange 2003 server. Now I'm experiencing problems getting RPC over HTTP to work. Here's what I've done so far.
Started to go through this guide as I used it in the past for the single domain controller and Exchange server and the guide worked flawlessly: http://www.petri.co.il/configure_rpc_over_https_on_a_single_server.htm
Now, I've looked at this guid to modify the configuration to allow for the second server (the seperate DC): http://www.amset.info/exchange/rpc-http-server.asp
To no avail does it work. When i run Outlook /rpcdiag i get only three lstings instead of the normal 5 or 6 that i get when i connect via the VPN (temporarily till RPC is fixed).
I only get three listings for Directory services, but never for mail services. It looks like it tries to connect but the line appears then disappears too fast that i can't even read what its saying.
Ive navigated to my external Exchange Website and that works just fine. Also checked the Https://mail.mydomain/rpc
and i get prompted for username /pass and i input them and i get a directory listing not valid, but no prompts about certificate errors, so that seems to work just fine.
Any other information I'm missing please feel free to ask. Thanks for all your help!
