Great Article. I ended up changing my scavenging on DNS to 2 days and 1 day refresh. This worked. DHCP leases are 8 hours.

I have 3 DNS servers. Each server is in its own subnet. It appears that the Primary DNS server is not deleting old records. We have duplicate IPs on one particular DNS server. I have scavenging turned on. &nbsp;<br />
Select the Enable automatic scavenging of stale records check box is checked. The Enable Aging and Scavenging for DNS &nbsp;is checked. The other 2 DNS servers are removing old records.<br />

Could the db be corrupt? Should I delete the duplicate records? That would be a time consuming task. <br />

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
