Local Users and Groups overview
http://technet.microsoft.com/en-us/library/cc785020(v=ws.10).aspx
You cannot use Local Users and Groups to view local user and group accounts once a member server has been promoted to a domain controller.
However, you can use Local Users and Groups on a domain controller to target remote computers (that are not domain controllers) on the network.
Use Active Directory Users and Computers to manage users and groups in Active Directory.
