Dns is not updating records
Please understand, the main thing that scavenging works on is the timestamp.
If there is no timestamp, such as a manually created, static record, it will not get scavenged.
This means that any authenticated user or computer can create a new object in the zone.
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.Well, I thought it’s time for an update and to just offer a summary in the beginning, because in this day and age, no one wants to read!A quick Facebook read the first line and click “Like,” seems to be the norm. And yea, I had to state Windows 2000 and newer, because this stuff doesn’t apply to older Windows versions.The way to get around this is you can configure DHCP’s Option 081 to update the record for all client, no matter if the client asks or not.To configure DHCP Option 081, you must look at the DHCP server properties, under the DNS Tab in DHCP properties. If you have Windows 2008 R2 or Windows 2012 R2, in addition to configuring the DNS tab to force registration, you still must configure credentials and add the server to the Dns Update Proxy group.
