"Index was out of range" New-AdDcCloneConfig error

Symptoms
You use the Virtualized Domain Controller (VDC) cloning feature that Windows Server 2012 introduced. You run the following Windows PowerShell cmdlet in order to clone a domain controller:
New-AdDcCloneConfigFile

When you do this, you receive warning and error messages that resemble the following:
Starting PDC test: Verifying that the domain controller hosting the PDC FSMO role is running Windows Server 2012 or later...
Passed: The domain controller hosting the PDC FSMO role (DC2-FULL.root.fabrikam.com) was located and running Windows Server 2012 or later.

New-ADDCCloneConfigFile : Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

+ ~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [New-ADDCCloneConfigFile], ArgumentOutOfRangeException
+ FullyQualifiedErrorId : ActiveDirectoryCmdlet:System.ArgumentOutOfRangeException,Microsoft.ActiveDirectory.Management.Commands.NewADDCCloneConfigFile
Cause
The Windows PowerShell cmdlet must run in from an elevated Windows PowerShell command prompt. Otherwise, your security token does not contain the Administrators group and cannot write to the c:\windows\ntds\dccloneconfig.xml file.
Resolution
Right-click the Windows PowerShell icon on the task bar, and then click Run as Administrator.
More information
Do not disable User Account Control (UAC) as a workaround for this behavior. In addition to the obvious administrative functionality, UAC is required in order to run Modern Application, provides Internet Explorer with its protected mode, and performs file and registry virtualization. Disabling UAC is not a Microsoft best practice.
