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.
Those records have an ACL on them to stop registered records from being hijacked by other hosts.
When DHCP is used to allocate IP addresses, the default configuration is shown below—which tells the DHCP server to register records in DNS on behalf of clients only if requested to do so by the client or if the client is unable to dynamically register (e.g., Windows NT 4.0).
Microsoft Dynamic DNS (DDNS) is a wonderful feature.
If you're waiting on DNS scavenging, there's no fast way to do it.
You, as a DHCP administrator, might want to enable DNS integration in order to automatically update the DNS records dynamically with the DHCP client computers’ information whenever the DHCP server assigns the IP address and other settings to them.
Since the DHCP server always assigns the dynamic IP addresses to the client computers which may change from time to time, and the DNS maintains the records of the information about the host names and their corresponding IP addresses, there must be some technology with the help of which the DNS server records can automatically get updated with the latest IP addresses that the DHCP server has assigned to the DHCP clients.
We have multiple hosts as of late that sucessfully pull a DHCP address and are domain machines that there is no A record being created for the host.
I can do a reverse lookup on the IP and that works but not name to IP.
