BUG: "Access is denied" Error Message When Making HTTPS Requests with ServerXMLHTTP

If the client certificate is not properly installed, you may receive the following error message along with the main error message:

Steps to Reproduce Behavior

The test requires two Web servers, ServerA and ServerB. One server is a target Web server with a valid SSL server certificate installed, and the other is a client Web server.

1. Install a valid SSL server certificate on ServerA.
2. On ServerA, save the following code as Targetpage.asp:

   <%@ Language="JScript" %>
   <%
   Response.Buffer=true ;
   
   
   var oxmldom = Server.CreateObject("MSXML2.DOMDocument.3.0");
   oxmldom.async=false;
   
   oxmldom.loadXML("<msg><id>TargetPage</id></msg>");
   Response.Write(oxmldom.xml);
   %>
   

3. Save the following code as Client.asp on ServerB, and make sure that ServerB is set with Medium or High application protection.

   <%@ Language="JScript" %>
   <%
   try
   {
   var Req = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0");
   var xmlDoc = Server.CreateObject("Msxml2.DOMDocument.3.0");
   
   xmlDoc.async = false;
   xmlDoc.loadXML("<msg><id>1</id></msg>");
   
   var URL = "https://targetserver/targetpage.asp";
   Req.open("POST", URL, false);
   Req.send(xmlDoc);
   
   Response.Write("<BR>Status = " + Req.status);
   Response.Write("<BR>responseText = " + Req.responseText);
   }
   catch( e )
   {
   Response.Write( "Exception!!<BR>");
   Response.Write(e.number + "<BR>");
   Response.Write(e.description + "<BR>");
   }
   %>
   

4. In Microsoft Internet Explorer, run the ASP page (http://ServerB/client.asp).
