I was able to get RDC working by putting in the IP address. However, all I can do is control the my laptop from the Mac. Not really what I want do. What I want to do is to be able to see the files on my PC in the Finder so that I can sync certain folders with those on my Mac as a way of a backup.
Even though I can see the PC on the Network and even though when I dbl clk its name a dialog comes up that already has the proper user and domain listed, I get the following message: The alias "[computer name]" could not be opened because the original item cannot be found.
