This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
This is the case for djbdns, for example. The operating system ensures that the last modification timestamp is updated whenever an administrator edits the database file, effectively automatically updating the serial number, and thus relieving administrators of the need to make two edits (in two different places) for every single change.
In the latter case, since Active Directory (rather than the DNS server) handles the actual replication of the database across multiple machines, the database can be modified on any server ("multiple-master replication"), and the addition or removal of a zone will be immediately propagated to all other DNS servers within the appropriate Active ...
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services . [ 1 ] [ 2 ] Originally, only centralized domain management used Active Directory.
Multi-master replication can be contrasted with primary-replica replication, in which a single member of the group is designated as the "master" for a given piece of data and is the only node allowed to modify that data item. Other members wishing to modify the data item must first contact the master node.
Like the DNS, it is implemented in two parts, a server service (that manages the embedded Jet Database, server to server replication, service requests, and conflicts) and a TCP/IP client component which manages the client's registration and renewal of names, and takes care of queries. Basically, Windows Internet Name Service (WINS) is a legacy ...
Servers that work together to provide this service are called Replication Partners. To control file replication: Use the Active Directory Sites and Services from Administrative Tools. Select the Sites container to view a list of sites. Expand the site that to be viewed. This will provide the list of servers in that site.
Distributed Component Object Model (DCOM) is a proprietary Microsoft technology for communication between software components on networked computers.DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure.
