Question : Exchange Setup RPC over https (following amset.info guide)

Hi,
Over the next few weeks I will be configuring a new internal network which will include an exchange server. My other colleague is installing the domain controllers and I am focusing on the exchange server.
Ok so I want to make exchange accessible to users from anywhere in the world (providing they have internet connection) I have done this on a SBS before. In this scenario the exchange was running on a DC. Which I think is the case for all SBS's . So my scenario now is 2 domain controllers 1 primary 1 secondary and I want exchange to be added as a member server.
I have been reading this article :
http://www.amset.info/exchange/rpc-http-server.asp

It seems pretty clear but I just wanted to confirm the registry changes. Please see below the changes I plan to make.

Also I plan to port forward ports 443 and 25 to the exchange.
Could someone please confirm these steps are accurate? I always like to have second opinion.

Hey Dan560,

The registry changes you describe look correct to me. Just remember you will need to make the Domain Controller changes on both DCs, and that both DCs should be Global Catalog servers.
