For domain controllers, due to the importance of keeping up to date and accurate SRV and other records, the Netlogon service will attempt to update these records every 60 minutes.

By default, on a computer that is running Windows XP/2003 or newer, the Default Registration Refresh Interval key value controls this (except Windows 2000, whichdoes not have this key but can be added), and is set by default to 1 day.
