    • When you connect to the console session of a terminal server on a Windows XP-based computer or on a Windows Server 2003-based computer, use the following commands as appropriate:
      • To make a Remote Desktop connection to the server, use the mstsc.exe /console command.
      • If you use the Remote Desktop Connection 6.1 client or a later version of the client, use the mstsc.exe /admin command.
