Moving Active Directory AD to a New Domain Controller DC

Since I don’t have to do this very often, but always seem to forget how to transfer the Schema Masterand Domain Naming Master, I decided to write it down, when it came up again as I transferred all the roles to my Windows 2012 server.

The following three FSMO roles can be migrated from Active Directory Users and Computers. Right mouse click on the domain and select Operations Masters. There is one tab for each of the three FSMO roles:

RID Pool Manager
Infrastructure Master

The following FSMO role can be transfered from Active Directory Domains and Trusts. Right mouse click on Active Directory Domains and Trusts, and select Operations Master.:

Domain Naming Master

For the Schema Master FSMO role, you first need to register a dll by executing the following command (Note: This only needs to be done once from an elevated command prompt.):

c:\> regsvr32 schmmgmt.dll

Then, you can add the Active Directory Schema Snap-In to a Microsoft Management Console (MMC). With the Snap-In added, ensure that the targeted domain controller is the one that you want to transfer the Schema Master role to. To change it, right mouse click on Active Directory Schema, under Console Root, and select Change Active Directory Domain Controller.. to select the domain controler you want to transfer the role to. Once that is done, right mouse click on Active Directory Schema, and select Operations Master to change the role.

If you do not have a different domain controller targeted, you will get the following message:

The current Active Directory Domain Controller is the Operations Master. To transfer the Operations Master to a different DC, you need to target Active Directory Schema to that DC.

And when you switch the target domain controller, you get the following, which is okay for what we want to do.:

Active Directory Schema snap-in is not connected to the schema operations master. You will not be able to permform any changes. Schema modification can only be made on the schema FSMO holder.

Windows 2012 R2 Remote Desktop Enabled Cannot RDP Connect

Windows 2012 RDP Remote Desktop Enabled but you Cannot Connect

You find that after you enable the Windows 2012 RDP or Remote Desktop Connection features to allow you to remote desktop into your new server, you are still unable to connect to the server.

The Cause

By default on new installs of Windows 2012 R2 the server firewall is enabled for TCP IP on Remote Desktop User Mode In TCP-IP.

The Fix

Enable the rule that permits access through the Windows Firewall.

1. Search for Firewall and open “Windows Firewall and Advanced Security”.

2. Find the rule “Remote Desktop – User Mode TCP-in” and ENABLE Rule

After working with Hyper-V and Snap shots, you may find that a previously working domain member machine gets this error message. This is because the Domain Controller will automatically update passwords of Machine Accounts every 30 days, and a restored snapshot may not match the new pass.

The solution

  1. On the effected client machine open PowerShell
  2. Run the following command “Reset-ComputerMachinePassword” or specify the credentials switch if the account your running PowerShell with doesn’t have the correct AD perms for the CMDlet “Reset-ComputerMachinePassword –credential Domain\Adaccount” (You will be prompted for the domain password).
  3. After running this give the client machine a restart

After Reboot, the server will function correctly.
