Citrix Published application manager allows you to quickly add or remove servers to or from your farm.
When you add servers to your citrix farm you can publish the applications within your farm to the new servers with just a few easy mouse clicks. Instead of going through the Citrix Management Console and selecting the properties of all your applications one by one and add them to the new servers.
Remove the binding from applications to a server so you can disable a server for published application for easy maintanance use. By removing the last server from an application the application will be disabled and NOT will not be destroyed.
