Explanation:

To allow the administrators to remotely manage the Network Load Balancing cluster through their Windows Vista client computers, you need to enable Windows Remote Management (WinRM) on the servers.

By using another computer running WindowsVista or Windows Server2008, you can use Windows Remote Shell that uses Windows RM to run command-line tools and scripts on a server running a Server Core installation.

Windows Remote Management (known as WinRM) is a handy new remote management service for Windows Server 2003 R2, Windows Vista, and Windows Server 2008. WinRM is the “server” component of this remote management application and WinRS (Windows Remote Shell) is the “client” for WinRM, which runs on the remote computer attempting to remotely manage the WinRM server.
