Hello All,  
  
I have a SBS 2003 server running at a client's office that I have attempted  
  
to enable RPC over HTTP on.  I have it working correctly in the office, but  
  
there is a problem when connecting to it over the Internet.  I have all of  
  
the correct ports (443, 80) open and forwarding to the server, but I get the  
  
generic 'Exchange Server Unavailable' message when trying to open Outlook  
  
(although it does ask me for my username and password, so I believe that it  
  
is initially trying to connect).  When I run RPCDIAG, under Interface I see  
  
nothing, and under Conn I see nothing.  
  
Any help is grealy appreciated!
