What bridgehead server in Active Directory?
The bridgehead server is a domain controller that has been either administratively assigned or automatically chosen to replicate changes collected from other domain controllers in the site to bridgehead servers in other sites.
What mechanism is used by active directory domain controller to indicate that it has unreplicated changes to communicate to its replication partners?
change notification
What is the difference between authoritative and non-authoritative restore?
A nonauthoritative restore is the default method for restoring Active Directory. To perform a nonauthoritative restore, you must be able to start the domain controller in Directory Services Restore Mode. After you restore the domain controller from backup, replication partners use the standard replication protocols to update Active Directory and associated information on the restored domain controller. An authoritative restore brings a domain or a container back to the state it was in at the time of backup and overwrites all changes made since the backup. If you do not want to replicate the changes that have been made subsequent to the last backup operation, you must perform an authoritative restore. In this one needs to stop the inbound replication first before performing the An authoritative restore.
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.
Why does the PlayStation move motion controller change color?
It changes colour for 2 reasons. 1) When Syncing the controller it will cycle through the colours to find the most suitable colour for the playing environment. This is to enable the highest possible visibility to the PlayStation Eye. 2) When the controller is being shared, the sphere can change colour to match each user to a different colour. This enables the users to identify whose turn it is easily.
When you perform a default restore of Active Directory it will be of this type?
Non-authoritative restore is the default method for restoring Active Directory. Non-authoritative restore of SYSVOL When you non-authoritatively restore the SYSVOL, the local copy of SYSVOL on the restored domain controller is compared with that of its replication partners. After the domain controller restarts, it contacts its replication partners, compares SYSVOL information, and replicate the any necessary changes, bringing it up-to-date with the other domain controllers within the domain. Perform a non-authoritative restore of SYSVOL if at least one other functioning domain controller exists in the domain. This is the default method for restoring SYSVOL and occurs automatically if you perform a non-authoritative restore of the Active Directory. If no other functioning domain controller exists in the domain, then perform a primary restore of the SYSVOL. A primary restore builds a new File Replication service (FRS) database by loading the data present under SYSVOL on the local domain controller. This method is the same as a non-authoritative restore, except that the SYSVOL is marked primary.
How can define primary domain controller or additional domain controller?
On Windows Server Systems, a domain controller (DC) is a server that responds to security authentication requests (logging in, checking permissions, etc.) within the Windows Server domain. 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. Additional Domain Controller (ADC) or Backup Domain Controller (BDC) is a backup computer hosting DC services to be used as a backup in case your primary DC goes down or is somehow unavailable. The Primary Domain Controller (PDC) and BDC synchronise their data on a regular basis so that either can be used as DC.
What are the five FSMO roles in Active Directory forest with one parent and two child domains?
There are five roles:They are further classified in two1. Forest RolesSchema Master - As name suggests, the changes that are made while creation of any object in AD or changes in attributes will be made by single domain controller and then it will be replicated to another domain controllers that are present in your environment. There is no corruption of AD schema if all the domain controllers try to make changes. This is one of the very important roles in FSMO roles infrastructure.Domain Naming Master - This role is not used very often, only when you add/remove any domain controllers. This role ensures that there is a unique name of domain controllers in environment.2. Domain RolesInfrastructure Master - This role checks domain for changes to any objects. If any changes are found then it will replicate to another domain controller.RID Master - This role is responsible for making sure each security principle has a different identifier.PDC emulator - This role is responsible for Account policies such as client password changes and time synchronization in the domain
Domain controller replication for 2008 server?
Replication and configuration setsActive Directory Lightweight Directory Services (AD LDS) uses replication to provide fault tolerance and load balancing for directory services. AD LDS uses a type of replication called multimaster replication. Through replication, AD LDS copies directory data updates that are made to a directory partition on one AD LDS instance to other AD LDS instances that hold copies of the same directory partition. AD LDS instances that hold copies of the same directory partition or partitions form a logical grouping called a configuration set.Multimaster replicationMultimaster replication simply means that you can make changes to directory data on any AD LDS instance. AD LDS replicates these changes to other members of the configuration set automatically. Multimaster replication is characterized by loose data consistency with convergence. When you make changes to data on a given directory partition at one AD LDS instance, replicas of that directory partition that are stored on other AD LDS instances become inconsistent with the most up-to-date replica of the directory partition (the partition where the changes were made). However, as changes get replicated through the configuration set, all partition replicas once again become identical; that is, they converge to the most recent data.Configuration setsAD LDS instances replicate data based on participation in a configuration set. All AD LDS instances that are joined to the same configuration set must replicate a common configuration directory partition and a common schema directory partition. AD LDS instances in a configuration set can also replicate any number of application directory partitions. AD LDS instances in a configuration set are not required to replicate all application directory partitions in the configuration set. A single AD LDS instance can replicate all-or any subset of-the application directory partitions in its configuration set. An AD LDS instance cannot, however, replicate an application directory partition from a different configuration set.Preventing replication conflictsWhat if two different users make changes to the same data on replicas of the same directory partition on two different AD LDS instances? In this case, each AD LDS instance attempts to replicate the changes, creating a conflict. To resolve this conflict, replication partners that receive these conflicting changes examine the attribute data that is contained in the changes, each of which holds a version and a time stamp. AD LDS instances accept the change with the higher version and discard the other change. If the versions are identical, AD LDS instances accept the change with the more recent time stamp.If two or more values in a multivalued attribute on an object are updated simultaneously on two different AD LDS instances, only one of the updated values will be replicated. In other words, simultaneous updates to a multivalued attribute that occur on two different AD LDS instances are considered to be in conflict, even if the updates apply to different values within the multivalued attribute. The only exception to this rule is for linked-value attributes (such as group memberships), which do allow for simultaneous updates to different values within the linked-value attribute.Replication topologyKnowledge Consistency Checker (KCC), a process that runs as part of each AD LDS instance, automatically constructs the most efficient topology for replication traffic to follow based on the network. The KCC regularly recalculates the replication topology to adjust for any network changes that occur in the environment.An AD LDS configuration set maintains its own replication topology, separate from any Active Directory Domain Services (AD DS) replication topology that might also exist. Directory partitions cannot be replicated between AD LDS instances and AD DS domain controllers.Ensuring replication securityTo ensure replication security, AD LDS authenticates replication partners before replication, and replication authentication always occurs over a secure channel. AD LDS uses Security Support Provider Interface (SSPI) to establish the appropriate authentication security level between replication partners. The method that is used for replication authentication within a configuration set depends on the value of the msDS-ReplAuthenticationModeattribute on the configuration directory partition. After replication partners have successfully authenticated, all replication traffic between the two partners is encrypted.The following table describes the security levels for replication authentication and the corresponding msDS-ReplAuthenticationMode attribute value for each security level. The default replication security level for a new, unique AD LDS instance is 1, unless a local workstation user account is specified as the AD LDS service account. If a local workstation account is specified as the AD LDS service account, the replication security level is set to 0To help maintain AD LDS replication security, the following best practices are recommended:Use the highest level of replication security that your environment can support.In AD DS environments, run AD LDS on member servers, rather than on domain controllers, whenever possible.If you run AD LDS on a domain controller in an AD DS environment, do not use the Network Service account as the AD LDS service account. Instead, use a domain user account that does not have administrative privileges.In workgroup and Windows NT 4.0 environments, do not use an account with administrative privileges as an AD LDS service account.Use separate configuration sets for applications with strict isolation requirements
