Dns not updating from dhcp server 2016 r2
Probably the best title for a blog post ever right?
Having seen and read about a lot of people struggling with DNS resolution problems with their clients on Essentials (2011/2012) networks, and also some dubious advice being given out for how to ‘resolve’ these problems i thought i would try and get into some deep level explanation of how, and why Essentials does what it does.
If we amend that DNS Service configuration, we find everything works as expected.
When the service has configured a NIC in a computer it will be shown in the registry under, No other information is held on the NIC in this registry key, other than the Name.
If a NIC is configured by the Service, but that entry no longer exists in the registry, than the Service will no longer attempt to configure that NIC, until the entry is manually recreated, or until the NIC is uninstalled and reinstalled.
The destination of the external DNS query is based on the configuration of the DNS Server service.
If your Essentials server is on it’s default settings you will find that your router is set as a forwarder in DNS.
