Here’s a chart showing when events occur with a 3-day No Refresh, 3 day Refresh, and 3 day Scavenging. You must be patient): If you look at the chart, based on scavenging settings of a 3 day No Refresh and 3 day Refresh, then it becomes eligible for scavenging the day after these two pass, so it will be the 7th day.

If there is a problem with PTRs getting updated even after configuring credentials, please see this article: DHCP server processes expired PTR resource records in Windows Server 2003 . Name squatting does not present a problem on a homogeneous Windows network where Active Directory® Domain Services (AD DS) can be used to reserve a name for a single user or computer.” DHCP Step-by-Step Guide: Demonstrate DHCP Name Protection“Name squatting occurs when a non-Windows-based computer registers in Domain Name System (DNS) with a name that is already registered to a computer running a Windows® operating system. Please understand, the main thing that scavenging works on is the timestamp.

The use of Name Protection in the Windows Server® 2008 R2 operating system prevents name squatting by non-Windows-based computers. If there is no timestamp, such as a manually created, static record, it will not get scavenged.

However, if you run dnscmd /Age All Records, it will timestamp all records, making them eligible for scavenging. When viewing a static record, it will show as the following: However, regarding static records, if you use force age all records using the dnscmd /Age All Records.

If the “Delete the record when it becomes stale” box was checked at time of the record creating, it will set a Time Stamp on it, which will make it eligible for scavenging. Rough formula to go by: No Refresh Refresh * 2 the point in time during the 3 day scavenge period.

With the default settings, a duplicate A record gets registered by DHCP with the client’s new IP.

This is because the client will not update itself due to the current record in DNS is beyond the lease period.Ace Fekay, MCT, MVP, MCITP EA, Exchange 2010 Enterprise Administrator, MCTS Windows 2008, Exchange 2010 & Exchange 2007, MCSE 2003/2000, MCSA Messaging 2003 Microsoft Certified Trainer Microsoft MVP: Directory Services Active Directory, Exchange and Windows Infrastructure Engineer Compiled 4/2006, recompiled 7/2009, & 1/4/201011/30/2011 – added DHCP credentials and DHCP/DNS tab properties screenshots.3/10/2012 – Added enabling DNS scavenging screenshots.8/22/2012 – Verified with a Microsoft enginner, we need to use the Dns Update Proxy group and configure credentials to work, not one or the other.
