# Add Server Instance Wizard: JBoss Server Instance Properties

You see this page of the Add Server Instance wizard when you are registering a JBoss Application Server instance. Use this page to specify the domain you are registering.

Select the domain from the Domain drop-down menu.

If you want to change a domain's port number, you must do so in the domain's `server.xml` file. By default, the port number is 8080. For example, if you are using the default domain, the domain's `server.xml` file is found here within the JBoss installation directory:

`\server\default\deploy\jbossweb.sar\server.xml`
