SYMPTOMS
When you use Internet Explorer to connect to a secure sockets layer (SSL) Web site, Internet Explorer may stop responding (hang), and you may receive the following error message or one similar to it:

A connection with the Server could not be established.



CAUSE
This problem can occur if Internet Explorer does not recognize the Root Authority of the SSL Web site, and the Auto Proxy configuration file is configured to return an alternate Proxy Server to the client. When Internet Explorer is using a proxy array and fails to match the Secured Servers Root Authority with the one in it's local store, Internet Explorer internally adds the proxy used to established the connection to the Internet Explorer BadProxy Server list. Internet Explorer then tries to contact the next proxy server in the array, and if the next server is unavailable, Internet Explorer tries to locate the server, and if this is not successful, it generates a navigation error.
