Windows dhcp server not updating dns
It might be easier to drop your scope lease time really low, then delete all the dynamic DNS records and let them get re-created.If you're waiting on DNS scavenging, there's no fast way to do it.In additon, hosts can change the records and then become the owner of the record.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.We have a set of Windows 2012R2 domain controllers which provide DNS and DHCP service for the network.I have an Ubuntu 14.04 server which is getting addresses via DHCP. In the Windows DHCP server, I have converted the lease to a reservation.However it is successfully giving out IP address to all IP enabled device and machine but when updating the DNS entry, only the Windows machine (workstations and server) gets their IP registered in the DNS server, therefore i cannot ping and access the other Linux machine apart from using IP address only.restarting the DNS (plus RELOAD the entry) and DHCP services doesn't help at all and also entering the DHCP assigned IP address into the DNS server caused more problem since the address is assigned to different host already by DHCP but not gets updated in the DNS server (only to non-windows machine).
Your DHCP clients need to be configured to register with DNS on update.
The default configuration for most Unix/Linux systems is to not update DNS.
