I have an iMac at home and a Windows 7 PC at work and I am trying to connect via Microsoft Remote Desktop 2.1.1. Both machines have been set up to receive remote connections, but I cannot get my iMac to connect. I get the following error message when I try: The Mac cannot connect to the Windows-based computer. This problem can occur if: The Windows-based computer is not set up to accept remote connections. The Windows-based computer is not turned on. The Mac, or the Windows-based computer is experiencing network problems. Try connecting to the Windows-based computer again, or contact your administrator. The networks work fine and the PC at work is fine. Does anyone have any idea how to fix this problem? I'm out of ideas.
