This topic helps you troubleshoot an unsuccessful RPC over HTTP connection. The topic explains how to verify that the RPC virtual directory is properly configured in Internet Information Services (IIS) so that IIS can connect to the RPC application on the RPC proxy server by using Secure Sockets Layer (SSL) protocol.

In the task, a client computer running Windows XP Service Pack 1 (SP1) or later is used to connect to the RPC virtual directory in IIS. The task uses Internet Explorer to test RPC and Internet Information Services (IIS) connection to confirm that the RpcProxy.dll file on the RPC proxy server is working correctly. To test that the RPC virtual directory is properly configured in IIS, follow one of the following procedures that best suits your scenario.

Test RPC proxy server, IIS functionality where Exchange Server 2003 runs on Windows Server 2003 or Windows Small Business Server 2003

  1. On the client computer, start Internet Explorer, type the fully qualified domain name (FQDN) address in Internet Explorer, and then click Go.

    For example, type: https://mail.contoso.com/rpc

    Note:
    Substitute the FQDN of your RPC proxy server for mail.contoso.com.
  2. Do one of the following depending on the message you receive:
    • If you receive the following message, click OK:
      You are about to view pages over a secure connection.
      Any information you exchange with this site cannot be viewed by anyone else on the Web.
    • If you receive a message that states that the certificate was issued by a company that you have not chosen to trust, make sure that the client computer trusts the root certification authority that issued the certificate.

  3. When you are prompted for your credentials, type your user name in the Universal Naming Convention (UNC) format, type your password, and then click OK.

    For example, type your user name in the domain\username format. You receive the following error message:

    The page cannot be displayed

    HTTP Error 403.2 – Forbidden: Read access is denied.
