Verify Replication between Domain Controlers

Sometimes, you always have a dude if one domain controler is or not is replicating correctly. If you want to know if this replication is woking fine, you only need to run this command in the server.

repadmin /showrepl servername /u: domainname \ username /pw:*

In this example I run the command in the second domain controler.

Operation Master Roles

If we want to understand who work a Forest with its domains and its Domain Controlers we need to know how work the Opertaion Master Roles

There are five operations master roles manage single-master operations in AD DS.

Two operations master roles exist in each forest:

The Schema Master, which governs all changes to the schema.

The Domain Naming Master, which adds and removes domains to and from the forest.

In addition to the two forestwide operations master roles, three operations master roles exist in each domain:

The Primary Domain Controller (PDC) emulator. The PDC emulator processes all replication requests from Microsoft Windows NT 4.0 backup domain controllers and processes all password updates for clients that are not running Active Directory–enabled client software.

The Relative Identifier (RID) master. The RID master allocates RIDs to all domain controllers to ensure that all security principals have a unique identifier.

The Infrastructure Master. The infrastructure master for a given domain maintains a list of the security principals from other domains that are members of groups within its domain.

Intalling Active Directory Domain Services

With Active Directory Domain Services (AD DS) server role, you can create a scalable, secure, and manageable infrastructure for user and resource management, and provide support for directory-enabled applications such as Microsoft Exchange Server.
AD DS provides a distributed database that stores and manages information about network resources and application-specific data from directory-enabled applications. A server that is running AD DS is called a domain controller. Administrators can use AD DS to organize elements of a network, such as users, computers, and other devices, into a hierarchical containment structure. The hierarchical containment structure includes the Active Directory forest, domains in the forest, and organizational units (OUs) in each domain. (Microsoft Reference)

If we want to install a new Forest in a company we need to start with a Domain Controler. Start in Server Manager Console and select " Add roles and features

Select Role-bases installation

Initial Configuration Windows 2012

After install Windows Server 2012, we need to configure the Server. Here there are a list with some recommendations.

1.Select the correct server name and add the computer into the domain (if you have one). The Server name is very important, and I recommend put a name that tell you the next characteristics:
- Location : 2 first leters the country
                  3 letter for the city
                  4 and 5, select a number for the office or floor where is the server. Starting with 01, 02 ...
- Rol         : 6 to x, an acronym that tell you what is the role for this server. (For example DC for a domain                          controler)
                 : a number that distinguishes the differents servers with the same role.

In this case, is the first domain controler in our company. We are in Dublin ( Ireland ). The name will be IRD01DC01

First of all we will go to Server Manager and Select " 1 Configure this local Server " (too easy)
