Packages can run only on servers that are designated as available in the NextGen® Background Business Processor Manager. By default, the NextGen® Background Business Processor makes all servers you add to the Server List available.
Select the Server List tab in the NextGen® Background Business Processor Manager.
Highlight the server in the list and right-click.
Select either Make Available or Make Unavailable from the shortcut menu.
Note: Another way to set availability for a server is to select or clear the Available? check box on the Server Properties window.
