Hi I have configure RPC over HTTP in single server enviroment in Exchange 2003 Standard But i unable to configure my outlook client with RPC proxy profile,I also aloow 135,80,443,1025-1030,1100-1192 port in my internet firewall but same problem please help me for same

I assume you've used a certificate for SSL and have deployed RPC over HTTPS, correct? The only port you would then need open is 443 for communication, and name resolution for the URL that will be used for the proxy (www.subhash.com/owa or whatever you plan to use). We can't resolve your problem without actual details. "same problem" doesn't tell us much.Missy

Presuming that your server hasn't been owned yet, you need to close all of those ports. You only need one - 443. Nothing else. 135 exposed to the Internet is simply an accident waiting to happen. Run it through the Microsoft test site at http://excra.com/ and see what that flags. Otherwise as Missy has already said, you will need to state exactly what you have done. RPC over HTTPS on Exchange 2003 either works, or it doesn't, but there can be many areas that can cause a problem. http://www.amset.info/exchange/rpc-http.asp Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK?
