About this Hands-on Lab

In this hands-on lab, you will learn how to identify Flexible Single Master Operations (FSMO) roles using PowerShell, how to move operations roles between domain controllers, and how to seize an operations role.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Locate the Flexible Single Master Operations Roles
  1. Determine the domain of the main-vm using SConfig.
  2. Locate the FSMO roles using netdom.
  3. Locate the FSMO roles using PowerShell.
  4. Identify the domain-level operations master using PowerShell.
Locate the FSMO Roles Using Graphic Administrative Tools

Next, we will identify the FSMO roles using Graphic Administrative Tools. In addition to validating this skill, we will prepare the environment for the third objective, where we will begin moving FMSO roles from main-vm to new-vm:

  1. Identify the domain naming master.
  2. Identify the schema master.
  3. View the domain-level operations masters.
Move the Infrastructure Master
  1. Move the infrastructure master (located on main-vm) to new-vm.
  2. Move the PDC emulator to the new-vm domain controller using PowerShell.
Seize FSMO Roles

Finally, we will seize some FSMO roles by going to new-vm. Once there, we should:

  1. Identify which operations roles are currently running on main-vm.
  2. Seize the schema master, domain naming master, and RID master from main-vm.
  3. Confirm the successful move of the seized roles.

Scenario

Welcome to Fiji! Our company, Sand, Sun, and Oddly Networking, Inc., is a global chain of luxury hotels that specializes in tropical locations. Concerned about high availability, the company would like to add another domain controller to their existing domain. In this hands-on lab, you will learn the steps needed to correctly assign FSMO roles, and how to seize an operations role in the case of domain issues.
