Hi Milad,By default Remote Desktop allows maximum two sessions to connect remotely. You have two options to connect to server.1. You can connect to console with "MSTSC /Console" command by typing in Run prompt.2. Disconnect any of the existing session by following below procedure.Go to Start ->All Programs -> Administrative Tools-> Terminal Services Manager. Connect to the Server and see the list of users who are connected to server remotely by terminal sessions. You can reset the Disconnected sessions. (You need to follow this procedure on any of the machine where Administrative Tools installed)BTW, this is Exchange Server - Admin forum, you would get better assistance in Windows forum onWindows related queries.Windows Forum:http://social.technet.microsoft.com/Forums/en/category/windowsserver/Amit Tank || MVP - Exchange || MCITP - Exchange 2007 || http://ExchangeShare.WordPress.com
