Domain name queries are handled by the DNS Servers. The most popular DNS server software is BIND 9.

DNS records are stored in DNS servers, which are part of a distributed network that manages domain name resolution. These servers can be authoritative, containing the definitive records for a domain, or caching, temporarily storing records retrieved from authoritative servers. When a user queries a domain, the DNS resolver checks its cache first and, if not found, queries the appropriate authoritative DNS server to fetch the records.
in Active Directory server roles, computers that function as servers within a domain can have one of two roles: member server or domain controller. A member server is a computer that runs an operating system in the Windows 2000 Server family or the Windows Server 2003 family, belongs to a domain, and is not a domain controller. Member servers typically function as the following types of servers: file servers, application servers, database servers, Web servers, certificate servers, firewalls and remote-access servers.
When a DNS server cannot resolve a query from its zone records or cache, it typically forwards the query to a higher-level DNS server, such as a root DNS server or a server authoritative for the domain in question. The root servers provide information about the authoritative servers for top-level domains (TLDs). The DNS server then recursively queries these TLD servers until it reaches the authoritative server for the specific domain, which can then provide the requested information. If the authoritative server is unreachable or does not have the record, the query will ultimately fail.

A conditional forwarder is a DNS server configuration that allows a DNS server to forward queries for specific domain names to designated DNS servers. This setup is useful in scenarios where an organization needs to resolve names in a different domain without fully integrating the two networks. By specifying which domains to forward and to which servers, organizations can streamline DNS resolution and improve efficiency for cross-domain queries. Conditional forwarders help maintain separation between different network environments while still enabling necessary communication.

A forwarder is a Domain Name System (DNS) server on a network used to forward DNS queries for external DNS names to DNS servers outside of that network. You can also forward queries according to specific domain names using conditional forwarders.A DNS server on a network is designated as a forwarder by having the other DNS servers in the network forward the queries they cannot resolve locally to that DNS server. By using a forwarder, you can manage name resolution for names outside of your network, such as names on the Internet, and improve the efficiency of name resolution for the computers in your network.

establishes a set of name server records in the DNS servers of the parent domain, indicating the IP addresses of DNS servers that are authoritative for the domain.
Member servers are computers that act as servers within a domain. It is a computer that runs in the operating system of the windows 2000 server family. Member server is in a domain but is not a domain controller. It can work as file server, application server, web server etc. Some of the key functions of member server are email management, faxing, file storage, web services etc.
Whenever mail servers talk to each other, they look for MX records at the destination's DNS. When a DNS server is setup for a domain and that domain has mail capabilities, their DNS server will have at least one MX record to denote which server handles mail. The root DNS servers for the internet denote the addresses for the SOA (start of authority) DNS servers for a particular domain.
