If you use a proxy server to access the web and the proxy server is not already configured in Microsoft Internet Explorer you will need to configure your proxy settings in this dialog.
Enter the proxy server address (i.e. my.proxy.com) and port (i.e. 8080). If you are not sure what to enter please contact your system administrator or ISP. If your proxy server requires authentication also enter your username and password.
To connect without a proxy server or to connect using the Microsoft Internet Explorer settings ensure that the Address field is empty.
