Answer:
When a new domain controller is created in a Windows Active Directory domain, several records are created or updated. These include:
1. SRV records - Used for domain service location, including LDAP, Kerberos, and Global Catalog services.
2. A record - A DNS record that maps the fully qualified domain name of the domain controller to its IP address.
3. NS record - A DNS record that identifies the domain controller as a nameserver for the domain.
4. PTR record - A reverse DNS record that maps the IP address of the domain controller to its fully qualified domain name.
These records help to ensure proper communication and functionality within the Active Directory domain.
