The Remote Desktops snap-in is a tool that administrators can use to administer multiple computers from a single remote location. By using the Remote Desktops snap-in, you can create Remote Desktop connections to multiple servers (including terminal servers) that are running Windows 2000 Server or Windows Server 2003 operating systems. You can also create connections to computers that are running the Windows XP Professional operating system. A navigable tree display provides easy switching between connections.
The Remote Desktops snap-in is included with Windows Server 2003. It is also included with the Windows Server 2003 Administration Tools Pack (Adminpak.msi). The Administration Tools Pack provides server management tools that enable administrators to remotely manage Windows 2000 Server-based or Windows Server 2003-based servers from a Windows XP-based or Windows Server 2003-based computer.
By default, when you connect to a Windows Server 2003-based computer, the Remote Desktops snap-in connects you to the console session of the computer that you specify in the connection. To run a specific program upon connection, create a new connection that specifies the program name, and ensure that the default behavior is not selected.
