How to Test Proxy Authentication

Updated July 19, 2017

Proxy servers are computers set up to funnel Internet connections through the server. Network administrators use a proxy server so Internet usage and Web page access can be controlled. You set up a username and password to limit who can connect to the proxy server. The settings are set up in the Internet Explorer Web browser. If you are able to connect, then you successfully test the proxy server authentication.

Click the Windows "Start" button and select "All Programs." Click "Internet Explorer" to open your Web browser. Click the "Tools" button at the top and select "Internet Options" to open a configuration dialogue window.

Click the "Connections" tab and click the link labelled "LAN settings." Another dialogue box opens. Click the "Use a proxy server for your LAN" option, then type your proxy server IP address in the text box. Click "OK" and click "OK" again in the main properties window.

Type an external website address in the Internet Explorer address text box. Press "Enter." If you are able to access an external website, your proxy server configurations are working. If not, you must re-enter the user's credentials on the proxy server.


Proxy server usernames and passwords are set up in the Internet Information Services Manager. Open this utility on your proxy server to reset the username and password for internal access to the proxy server.
