How to Use Powershell to Connect to a Remote Computer
Powershell is a command line utility in the Windows Server 2008 operating system that gives users the ability to perform a broad range of commands, much more than are offered in the standard Command Prompt application. From within Powershell, you can launch the Remote Desktop Connection application, which allows you to connect to a remote computer from your server.
Open the Powershell program from your Windows Start Menu.
Type "mstsc /v:computer_name" ("computer_name" is the name or IP of the remote computer you're connecting to into the Powershell window).
Press "Enter," type in your login information and press "Enter" again to connect to the remote computer.
