We are setting up a new office and need to implement rpc over http. All the back end configuration on the server has been done and the client machines can connect to the exchange server through a vpn. We want to eliminate the vpn hence the need for RPC. I went ahead and set up all the outlook 2003 clients with the correct server information and installed the server certificate on them as well but it will not connect. The server certificate says exchange.mydomain.com but it says it was issued by server5.mydomain.com. My question is do the issued to field and the issued by field have to be the same? If that is the case I would need to change my CA to the exchange server, correct? Thanks in advance.
