Directory pruning interval

Specifies how often the pruning service on a domain controller contacts computers to verify that their printers are operational.

The pruning service periodically contacts computers that have published printers. If a computer does not respond to the contact message (optionally, after repeated attempts), the pruning service "prunes" (deletes from Active Directory) printer objects the computer has published.

By default, the pruning service contacts computers every eight hours and allows two repeated contact attempts before deleting printers from Active Directory.

If you enable this setting, you can change the interval between contact attempts.

If you do not configure or disable this setting the default values will be used.

Note: This setting is used only on domain controllers.


Supported on: At least Windows 2000

The Pruning Interval determines the period of time the pruner

sleeps between checks for abandoned PrintQueues.
