You can start the administration server on Windows in any one of the following ways:
Select the Start menu -> Programs -> Sun Microsystems -> Sun Java System Web Proxy Server 4, and choose Start Admin Server
From the Services item in the Control Panel
At the command prompt, go to the proxy-admserv directory under your server root directory and start the administration server by typing start.
Once you have started the administration server, you need to connect to it.
In the above URL, use the port number of the administration server that you specified during installation. You will be prompted for a user name and password.
Enter your administration user name and password. The Server Administration page appears.
You can now configure your Proxy Server. For more information on configuring and using the Proxy Server, see the Proxy Server Administration Guide.
