Maybe I'm missing out on a very BASIC setting, but I'm trying to setup the 'Remote Desktop Connection' between computers in my house, and no matter what computers I'm trying to have a connection the error message: 'The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection. Please try your connection again later. If the problem continues to occur, contact your administrator.' How do I enable remote connections??
