Domain controllers play an important role in the functioning of a network. They are responsible for storing and providing access to the DNS database, which is used to resolve domain names.

DNS health is important for all domain controllers. A domain controller that is not functioning properly can cause problems for users and network administrators.

To ensure that a domain controller is functioning properly, you can use the Dnscmd tool to check its DNS health.

To check a domain controller’s DNS health, you can use the following command:

Dnscmd /Query /ComputerName: /Show DNS Health

You can also use the following command to check the A, PTR, and MX records for a domain controller:

Dnscmd /Query /ComputerName: /Show DNS Record

You can also use the following command to check the status of the DNS server:

Dnscmd /Query /ComputerName: /Show DNS Server Status

You can also use the Dnscmd tool to reset a domain controller’s DNS settings.

Conclusion
