RPC-over-HTTP Authenticates But Won't Connect

Okay - Setup RPC-over-HTTP using the instructions on Petri (http://www.petri.co.il/configure_rpc_over_https_on_a_single_server.htm) and everything tested out on the local network, even with the local exchange ports disabled (So it was forced to use port 443).

My problem comes in when I move outside the network; it pulls up the login diialog and everything looks like it connects but then all the connections break. Now I forwarded port 80, 443, 6000-6004 to the exchange server and I turned off everything on the firewall (IPS, Content Filtering, Gateway Virus).

Any ideas?

If the certificate used for SSL is 'home-made', you need to add that certificate to the local trust store on your computer for it to work. The easiest way to check this, is to connect to your exchange server OWA using https://..... and seeing what IE throws up to you. Based on this, than you can follow as isaman07 is asking about

That was the issue, I self issued a cert and although it was done correctly (the name on the cert matched the full name it was connecting to) it wasn't actually signed by a real authorative. Went out and bought a SSL, thew it into IIS and it's working perfect!

Thanks guys!
