Transfer Active Directory FSMO Roles via PowerShell

Sometimes a domain controller (DC) just needs to be decommissioned for whatever reason, let’s say an upgrade, or corrupted VM and the roles are now seized.. nevertheless, moving the FSMO (Flexible single master operation) roles can be done via the UI, however if you want to speed things up and do it with PowerShell, here is how to that.

In my scenario, I am decommissioning my Hyper-V server which at the time was acting as the primary DC. Now that it is being decomm’ed I need to transfer the FSMO roles to another DC. The destination DC is “DC01” in this case.

Move-ADDirectoryServerOperationMasterRole -Identity "DESTINATION DC" -OperationMasterRole 0,1,2,3,4

You have the option here to specify a numerical value or specifying the role itself. See below for the number assoicated to each roles. You could input each role, or as I did, just input the number(s).

PDCEmulator or 0
RIDMaster or 1
InfrastructureMaster or 2
SchemaMaster or 3
DomainNamingMaster or 4

To verify the FSMO roles have been transferred, run the netdom query fsmo command.

Hyper-V 2016 Linux Ubuntu PXE Network Boot Error

If you’re like me, you want to run Linux on your Hyper-V 2016 host, in my case I am attempting to run a Linux Ubuntu 16.04.1. Booting from an ISO, I kept getting the same error over and over. “PXE Network Boot using IPv4 ( ESC to cancel ) Performing DHCP Negotiation….“. After realizing it wasn’t the ISO media. It wasn’t the size of the VHDX. It wasn’t the memory/vCPU or vNIC configuration. It wasn’t even due to the fact it was a Generation 1 or Generation 2 VM…. It was Secure Boot function.

Solution

  1. Stop the VM
  2. Go to its Settings
  3. Within Hardware > Select Security > Disable/UncheckEnable Secure Boot” > Start your machine back up!

Yay!
