Administrators may want to permanently remove a host from the farm. This is normally required if the host is no longer being used 's responsibilities as a Worker has come to an end, or no longer exists.
Removing a Worker host places it in a list of banned hosts and the Supervisor will no longer track the host, even if auto-discovery would normally register such a host with the Supervisor.

A banned worker will be unable to re-register with the supervisor until its ban has been cleared. |
