exchange newb - RPC over HTTP

newb question, hang with me here:

I need to set up an exchange server for RCP over HTTP.  I have a win2k3 box running exchange 2003.  One DC is a 2k3 box that is the GC, the other DC is win2k.  I didn't set up the exchange server, and Im just figuring it all out.

Question 1:  How do I tell what topology was used in setup.  ie front-end back-end...If I've only got one exchange box, does that mean front-end and back-end are the same or on the same box?

Question 2:  To set up RPC over HTTP, do I need to set up and ISA server as my front-end proxy to get RPC over HTTP to work.

Thanks in advance

1. If you only have a single Exchange Server, it's a combined Front-end and back-end server. It will also need to be the RPC over HTTP proxy.

2. No, you don't need ISA, but using ISA will make it more secure. You can install the RPC over HTTP Proxy service on the Exchange Server.
