Enter a valid hostname (usually a computer's name on network) or a valid computer's IP Address you want to work to.
Current Host is shown on top. If you uncheck Main Level option, all new hosts you define will be added as contained by current host shown, as a child, in case you want to define a group of hosts.
Please Note: Hosts will not be saved until you close the Connect to Remote Shutdown window. If you want to discard all changes, just hold the SHIFT key while closing window.
