  1. Challenge

    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.

  2. Challenge

    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.

  3. Challenge

    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.

  4. Challenge

    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.
