A secondary server for a zone uses an automatic updating mechanism to maintain an identical copy of the primary server's database for a zone. Examples of such mechanisms include DNS zone transfers and file transfer protocols. DNS provides a mechanism whereby the primary for a zone can notify all the known secondaries for that zone when the ...
A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against its database. The most common types of records stored in the DNS database are for start of authority ( SOA ), IP addresses ( A and AAAA ), SMTP mail exchangers (MX), name servers (NS), pointers for reverse DNS ...
Authoritative servers can publish content that originates from primary data storage (such as zone files or databases connected to business administration processes)--sometimes also called 'master' servers--or can be secondary (or slave) servers, republishing content fetched from and synchronized with such primary servers. Servers with a ...
On Microsoft Servers, a domain controller (DC) is a server computer [1] [2] that responds to security authentication requests (logging in, etc.) within a Windows domain. [3] [4] A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
Returns all records of all types known to the name server. If the name server does not have any information on the name, the request will be forwarded on. The records returned may not be complete. For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned.
DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers .
For example, the primary might perform some computation, streaming a log of updates to a backup (standby) process, which can then take over if the primary fails. This approach is common for replicating databases, despite the risk that if a portion of the log is lost during a failure, the backup might not be in a state identical to the primary ...
The software and operating system used to run a domain controller usually consists of several key components shared across platforms.This includes the operating system (usually Windows Server or Linux), an LDAP service (Red Hat Directory Server, etc.), a network time service (ntpd, chrony, etc.), and a computer network authentication protocol (usually Kerberos).
