What is the TTL on the problematic DNS records? &nbsp;TTLs are often set quite long. &nbsp;If it is, say, 3600 seconds then it would take an hour for an old record to flush and become eligible for updating. &nbsp;If it is a day, it could take (in the worst case) 24 hours before it was eligible for an update on systems with cached DNS information.

Check your server's DNS event log for events 2501 and 2502. One of these two events will be logged every time a scavenging pass is made. If you can't find either event, your server is not attempting to scavenge, likely because something isn't configured properly.

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.
