Set scavenge interval

This policy setting determines the interval at which Netlogon performs the following scavenging operations:- Checks if a password on a secure channel needs to be modified and modifies it if necessary. – On the domain controllers (DC) discovers a DC that has not been discovered. – On the PDC attempts to add the [1B] NetBIOS name if it hasn’t already been successfully added. None of these operations are critical. 15 minutes is optimal in all but extreme cases. For instance if a DC is separated from a trusted domain by an expensive (e. g. ISDN) line this parameter might be adjusted upward to avoid frequent automatic discovery of DCs in a trusted domain. To enable the setting click Enabled and then specify the interval in seconds.
