No, you cannot have multiple schema masters or multiple PDC emulators in the same domain or forest. Each Active Directory forest has only one schema master, which is responsible for managing changes to the schema, and only one PDC emulator per domain, which acts as a primary time source and handles password changes and group policy updates. Having multiple instances of these roles would lead to conflicts and inconsistencies within the directory.
The term "master key" often refers to a key that can open multiple locks, typically within a specific system or building. In security systems, master keys are designed through a controlled keying process that allows for hierarchical access. Knowledge of a master key typically comes from the locksmith or security system designer, who sets up the keying arrangement, ensuring that authorized individuals have access while maintaining security for others. Access to a master key should be strictly managed to prevent unauthorized use.
A master case is a comprehensive legal case that encompasses multiple related cases or issues, often serving as a central reference point for managing and resolving them. It is commonly used in complex litigation, such as class actions or multi-district litigation, where various claims share common questions of law or fact. The master case helps streamline the legal process, ensuring consistency in rulings and efficient case management.
Yoda did not have a master, he was the ultimate jedi. While I agree Yoda was the ultimate jedi, he had a master. His master's name was Jedi Master N'Kata Del Gormo.
Jedi Master Kit Fisto's only known master is Jedi Grand Master Yoda.
Splinter is the rat that is the TMNT's master.
A forest in Active Directory contains a total of five FSMO (Flexible Single Master Operation) roles. These roles are divided among domain controllers within the forest: one Schema Master, one Domain Naming Master, and each domain within the forest has one RID Master, one PDC Emulator, and one Infrastructure Master. Therefore, while there is only one Schema Master and one Domain Naming Master for the entire forest, there can be multiple instances of the other three roles, depending on the number of domains present.
1 Domain Naming Master, 1 Schema Master, 1 PDC Emulator, 1 Infrastructure Master, 1 RID Master
The domain controller is only of one type but it can have different roles Domain Naming master RID master PDC Schema Master Infrastructure master Schema master (forest wide): The Schema Master controls all updates to the Schema within the forest. Domain Naming Master (forest wide): The Domain Naming Master role is responsible for the creation and deletion of domains in the forest. PDC Emulator (domain wide): The PDC emulator role provides backwards compatability for Windows NT backup domain controllers (BDCs), the PDC emulator advertises itself as the primary domain controller for the domain. It also acts as the domain master browser and maintains the latest password for all users within the domain. Infrastructure Master (domain wide): The Infrastructure Manager role is responsible for updating references from objects within its domain with objects in other domains. RID Master (domain wide): The RID Master manages the Security Identifier (SID) for every object within the
If you only have one domain in your forest, nothing will be wrong. If you do however have multiple domains in you forest, and you put your GC and infrastructure master on the same machine, things can go horribly wrong. This is because GC and Infrastructure Master use the same NTDS.dit file, changes will be changed by GC and Infrastructure Master checks the NTDS.dit and doesn't see any change, because GC already changed the NTDS.dit Only way you can run GC and infrastructure Master on the same machine in a multiple domain forest is to enable GC on all domain controllers... greets

A Forest Wide FSMO (Flexible Single Master Operation) role is a specific function in Active Directory that is responsible for certain critical tasks across the entire forest, as opposed to being limited to a single domain. There are five FSMO roles in total, with the Forest Wide roles being the Schema Master and the Domain Naming Master. The Schema Master manages changes to the Active Directory schema, while the Domain Naming Master oversees the addition and removal of domains within the forest. These roles are essential for maintaining the integrity and structure of the Active Directory environment.
What is the RID Master role? The RID Master is one of the operations master roles that exist in each domain in a forest. It controls the sequence number for the domain controllers within a domain. It provides a unique sequence of RIDs to each domain controller in a domain. When a domain controller creates a new object, the object is assigned a unique security ID consisting of a combination of a domain SID and a RID. The domain SID is a constant ID, whereas the RID is assigned to each object by the domain controller. The domain controller receives the RIDs from the RID Master. When the domain controller has used all the RIDs provided by the RID Master, it requests the RID Master to issue more RIDs for creating additional objects in the domain. When a domain controller exhausts its pool of RIDs, and the RID Master is unavailable, any new object in the domain cannot be created
Flexible Single Master Operations servers. They are servers that every Active Directory needs that serve a single purpose. Here are the FSMO servers: Schema Master Domain Naming Master Infrastructure Master Relative ID Master PDC Emulator Those are the five FSMO server rolls that get assigned to 1 or more domain controllers in each domain. Schema and Domain Naming Master will have only 1 server per AD Forest.
In Windows 2000 Server, the five operation master roles, also known as Flexible Single Master Operation (FSMO) roles, are: Schema Master - Manages changes to the directory schema. Domain Naming Master - Controls the addition and removal of domains in the forest. RID Master - Allocates RID pools to domain controllers within a domain. PDC Emulator - Acts as a primary domain controller for backward compatibility and handles password changes and time synchronization. Infrastructure Master - Updates references from objects in its domain to objects in other domains.
The infrastructure masters job is to compare objects of the local domain against objects in other domains of the same forest. If the server holding the infrastructure master is also a global catalog it won't ever see any differences, since the global catalog holds a partitial copy of every object in the forest itself. Therefore the infrastructure master won't do anything in its domain. However if every DC in the Domain is also global catalog server there's no job for the IM since the GC already knows about the objects of other domains. So if you look at the job the IM has to do, it's pretty clear that it may reside on a GC if it's a single domain forest (no need to pull updates from other domains). It's also pretty clear that it may reside on a GC if it's in a multiple domain forest but every DC in the domain where the IM runs on the GC are also GCs (no need to pull updates since the GC knows everything).
Single-master replication can make it difficult for administrators to manage Active Directory objects, especially if they are located in remote offices and must work over a slow wide area network (WAN) link. To address this problem, Active Directory uses multiple-master replication, in which it is possible to make changes to domain objects on any domain controller, which replicates those changes to all of the other domain controllers.
