Transferring FSMO Roles in Windows Server 2008

The five FSMO roles are:

  1. Schema Master
  2. Domain Naming Master
  3. Infrastructure Master
  4. Relative ID (RID) Master
  5. PDC Emulator

The FSMO roles are going to be transferred, using the following three MMC snap-ins :

  • Active Directory Schema snap-in : Will be used to transfer the Schema Master role
  • Active Directory Domains and Trusts snap-in : Will be used to transfer the Domain Naming Master role
  • Active Directory Users and Computers snap-in : Will be used to transfer the RID MasterPDC Emulator, and Infrastructure Master roles

Note: The following steps are done on the Windows Server 2008 machine that I intend to set as the roles holder ( transfer the roles to it )

Lets start transferring the FSMO roles.

  • Using Active Directory Schema snap-in to transfer the Schema Master role You have to register schmmgmt.dll in order to be able to use the Active Directory Schema snap-in 
  1. Click StartRun
  2. Type regsvr32 schmmgmt.dll
  3. Click OK A popup message will confirm that schmmgmt.dll was successfully registered. Click OK
  4. Click Start Run, type mmc, then click OK
  5. Click File > then click Add/Remove Snap-in…
  6. From the left side, under Available Snap-ins, click on Active Directory Schema, then click Add > and then click OK

  7. Right click Active Directory Schema, then click Change Active Directory Domain Controller…
  8. From the listed Domain Controllers, click on the domain controller that you want to be the schema master role holder and then click on OKYou will receive a message box stating that the schema snap-in is not connected to a schema operations master. That is for sure, as we have not yet set this Windows Server 2008 domain controller as a Schema Master role holder. This will be done in the next step. Click OK
  9. In the console tree, right click Active Directory Schema [DomainController.DomainName], and then click Operations Master…
  10. On the Change Schema Master page, the current schema master role holder will be displayed ( ex. DC.SOMETHING.NET) and the targeted schema holder as well (ex. DC2K8.SOMETHING.NET). Once you click Change, the schema master holder will become 
    DC2K8.SOMETHING.NET
    , click Change

    Click Yesto confirm the role transfer

    The role will be transferred and a confirmation message will be displayed. Click OK

    Then click Close, as you can see in the below snapshot, the current schema master is DC2K8.SOMETHING.NET

  • Using Active Directory Domains and Trusts snap-in to transfer the Domain Naming Master Role
  1. Click Start Administrative Tools > then click Active Directory Domains and Trusts
  2. Right click Active Directory Domains and Trusts, then click Change Active Directory Domain Controller…
  3. From the listed Domain Controllers, click on the domain controller that you want to be the Domain Naming master role holder and then click onOK
  4. Right click Active Directory Domains and Trusts, then click Operations Master…
  5. On the Operations Master page, we are going to change the Domain Naming role holder from DC.SOMETHING.NET to DC2K8.SOMETHING.NET, Click ChangeClick YES to confirm the transfer of the Domain Naming roleThe role will be transferred and a confirmation message will be displayed. Click OK , then click Close


Till now, we have successfully transferred two FSMO roles, the Schema Master role and the Domain Naming role. The last three roles can be transferred using a single Snap-in.

 

  • Using Active Directory Users and Computers snap-in to transfer the RID Master, PDC Emulator, and Infrastructure Master Roles
  1. Click StartAdministrative Tools > then click Active Directory Users and Computers
  2. Right click Active Directory Users and Computers, then click All TasksOperations Master…
  3. You will have three Tabs, representing three FSMO roles (RID, PDC, Infrastructure). Click the Change button under each of these three tabs to transfer the roles.Click Yes to confirm the role transferThe role will be transferred and a confirmation message will be displayed. Click OK

    As for the Infrastructure role, once you click on the Change button you will receive the below message

    By default, when you first install your first Domain Controller, it holds the five roles and beside that it is a Global Catalog. If your environment is a multi-domain/forest, then you should think about structuring your FSMO roles and transfer the Infrastructure role to a none Global Catalog domain controller. Else if you have small number of domain controllers ( ex. two domain controllers) then you should not worry about this. ClickYes

  4. The Tabs should now look like this:

 

That’s it, by now, you have successfully transferred the five FSMO roles to the Windows Server 2008 Domain Controller.

 

Summary

 

There are five FSMO roles in a forest, to transfer any of these roles you have to use the appropriate Active Directory snap-in.
