Bridgehead servers are used in Active Directory replication to reduce network traffic by serving as intermediaries between sites, thus minimizing the number of replication connections needed. They also help control the flow of replication data by efficiently routing updates between domain controllers in different sites. This ensures that changes to the directory are replicated efficiently across the network.
The long form for AD is Anno Domini, which is a Latin term meaning "In the year of our Lord." It is used to denote years after the birth of Jesus Christ.
The ad slogan "Fun for Anyone" is associated with the company Nintendo. It is a slogan used to promote their video games and consoles as being enjoyable for people of all ages.
BP is a way of expressing the age of an object, as compared to BC or AD. BP is based on the disintegration of carbon. A rough formula for finding BP age from an AD is today's year minus 1950 = a number to subtract from the AD date. For example, an object is dated at 1,000 AD. It is now 2008, therefore 2008 - 1950 = 58. The object date 1,000 AD - 58 = 942 BP. Basically BP is approximately the BC date plus 1950 and the AD date minus today's year minus 1950.
The first distilled alcohol known as "aqua vitae" was produced at Montpellier medical school in 1300 AD. Aqua vitae was believed to have medicinal properties and was used as a treatment for various ailments.
AD 79, AD 1944, and many other times.
Supported Tools are used to Maintain AD Services. used to handle replication as well. Ntdsutil.exe to make changes or administrate to AD database. replmon and repadmin to monitor and administrate replication. netdiag to monitor network.
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

The server which is domain controller only that server has AD installed on it others are just member servers which does not have AD on them but has only windows 2003 OS.So you can make changes in ad related servers or DCs only. You can install AD on member server that is the only thing you can do on member server related with Ad
IT purely depends on the Size of the organization, users and the work they are doing. The servers could be print server, file share, ad servers,sharepoint server,database servers etc..

There are2 types of replication.1 AD replication2 Sysvol replicationAD replication uses RPC.Sysvol uses DFS Replication (DFSR) service, if Domain is at2008 functional level and all DCs are WIndows Server2008 or higher OS version. If domain functional level is2003, Sysvol uses NT File Replication Service (NTFS)
