In the tree component, expand the Configurations node.
Select the instance to configure:
Expand the HTTP Service node.
Select the Virtual Servers node.
On the Virtual Servers page, check the box next to the name of the virtual server to be deleted.
It is possible to delete the __asadmin virtual server, but this is not recommended. If you plan to do so, first copy the virtual-server elements of the Application Server’s domain.xml file to a safe place so that the settings can be restored if needed.
