  1. Find out what your primary domain controller (PDC) is for your domain by executing the following powershell commands from any machine in the domain
    1. [System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().RootDomain.PdcRoleOwner.Name
      PowerShell - PdcRoleOwner
  2. Login to your primary domain controller
  3. Open up a command prompt/powershell window with administrative privileges
