What is knowledge consistency check in Active Directory?
The Knowledge Consistency Checker (KCC) is a dynamic-link library (DLL) that runs as a distributed application on every domain controller. The KCC on each domain controller modifies data in its local instance of the directory in response to forest-wide changes, which are made known to the KCC by changes to data in the configuration directory partition. The KCC generates and maintains the replication topology for replication within sites and between sites by converting KCC-defined and administrator-defined (if any) connection objects into a configuration that is understood by the directory replication engine.
What is the ISTG?
Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG). Krishna Pothula Answer: Intersite Topology Generator (ISTG), which is responsible for the connections among the sites. By default Windows 2003 Forest level functionality has this role.
What is KCC in active directory?
knowledge consistency checker- it generates the replication topology by specifying what domain controllers will replicate to which other domain controllers in the site. The KCC maintains a list of connections, called a replication topology, to other domain controllers in the site. The KCC ensures that changes to any object are replicated to all site domain controllers and updates go through no more than three connections. Also an administrator can configure connection objects.
What is the full name of kcc?
KCC comes under Active Directory Section.KCC:Knowledge Consistency Checker.As soon as You install the second domain controller in a forest, a process called the knowledge consistency checker begins running on every domain controller. The KCC is responsible for generating the replication topology and dynamically handling the changes and failures within the replication topology.By default the KCC on every domain controller recalculates the replication topology for every 15mins.The more the replication topology, the more the processing power it takes to perform.Within a Site, a Windows server 2003 service known as the KCC automatically generates a topology for replication among the domain controllers in the domain using a ring structure.Th Kcc is a built in process that runs on all domain controllers.The KCC analyzes the replication topology within a site every 15 minute to ensure that it still works. If you add or remove a domain controller from the network or a site, the KCC reconfigures the topology to relect the change.AnswerKCC is Knowledge Consistency Checker, which creates the connection object that links the DCs into common replication topology and dictates the replication routes between one DC to another in Active Directory forest.
When planning a new network the administrator is interested in a physical topology that is used more often than any other which topology is the administrator considering?
star topology
What component automatically creates replication links between domain controllers in the same site and schedules their replication activities?
Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG). Krishna Pothula Intersite Topology Generator (ISTG), which is responsible for the connections among the sites. By default Windows 2003 Forest level functionality has this role. ... Or the Distributed File System (DFS).
What does KCC create between multiple domain controllers within a site?
the site links are created by KCCKCC and Topology GenerationThe KCC is a built-in process that runs on all domain controllers. It is a dynamic-link library that modifies data in the local directory in response to systemwide changes, which are made known to the KCC by changes to the data within Active Directory. The KCC generates and maintains the replication topology for replication within sites and between sites.The KCC has two major functions:Configures replication connections (connection objects) between domain controllers. Each connection object defines incoming replication from a replication partner. Within a site, each KCC generates its own connections. For replication between sites, a single KCC per site generates all connections between sites.Converts the connection objects that represent inbound replication to the local domain controller into the replication agreements that are actually used by the replication engine.By default, the KCC reviews and makes modifications to the Active Directory replication topology every 15 minutes to ensure propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
What is the default DFS replication topology?
by default, replication groups use a full mesh topology, which means that every member in a group replicates with every other member.
When replicating information between sites Active Directory will designate a server in each site to act as a gatekeeper in managing site-to-site replication?
if you have not selected any DC as bridgehead server then it automatically follows ISTG - InterSite Topology Generator,chooses its own DC to replicate and if this link is down makes another but if you define bridgehead server,in that case if the link fails the replication stops.

What is knowledge consistency checker KCC in windows server 2003?
The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite). The KCC also dynamically adjusts the topology to accommodate new domain controllers, domain controllers moved to and from sites, changing costs and schedules, and domain controllers that are temporarily unavailable.
What is replmonexe?
The Replmon utility was introduced with Windows Server 2000 as a Support Tools utility. The utility worked on both 32 bit and 64 bit operation systems. In Windows Server 2003 the utility was only available in the 32 bit version of the Support Tools. The preferred tool for managing and troubleshooting replication is the Repadmin.exe utility for Windows Server 2008 and Windows Server 2008 R2. With that said, the Windows Server 2003 SP2 Support Tools can be installed on a 32 or 64 bit computer and will allow you use Replmon Replmon.exe is the Active Directory Replication Monitor This tool enables administrators to view the low-level status of Active Directory replication, force synchronization between domain controllers, view the topology in a graphical format, and monitor the status and performance of domain controller replication. ReplMon can be used to do the following: See when a replication partner fails. Display replication topology. To view the history of successful and failed replication changes for troubleshooting purposes. To view the properties of directory replication partners. To Create your own applications or scripts written in Microsoft Visual Basic Scripting Edition (VBScript) to extract specific data from Active Directory. To view a snapshot of the performance counters on the computer, and the registry configuration of the server. To Generate status reports that include direct and transitive replication partners, and detail a record of changes. To Display changes that have not yet replicated from a given replication partner. To Display a list of the trust relationships maintained by the domain controller being monitored. To Display the metadata of an Active Directory object's attributes. To Monitor replication status of domain controllers from multiple forests. To Find all direct and transitive replication partners on the network. To Poll replication partners and generate individual histories of successful and failed replication events. To Force replication. To Trigger the Knowledge Consistency Checker (KCC) to recalculate the replication topology.
