Check the DNS client service of the new computer The DNS client service is the service that does the actual update.
If this service is stopped for some reason no update will proceed.
You just replaced a computer; the old computer is off the network and had held the DHCP IP address of 192.168.0.10.
You bring the new computer online and it obtains a DHCP lease for the same IP address. However, when you try to resolve the name of the new computer, the old computer's name still comes up. Here's how we'll start the troubleshooting process: 1.
The following list illustrates a typical example of how a private DNS update leaks out to the global Internet. The DHCP client first sends a query to its local domain name server (LDNS) and asks for the authoritative server for the zone of its domain name (step 3).
Once the DHCP client receives a response (step 4), it sends the update to the indicated server (step 5).
However, in many cases when the DHCP and DNS configurations have inconsistencies, the LDNS may direct the DHCP client to a place outside the local scope, resulting in leakage of private DNS updates to the global network.
