Hello! I I bought a MBPR a week ago and until this day I can't find the solution for the networking problem. We have a windows based network, the main computer has a windows 7 installed. ON my Mac I can see the "MainServer" on my finder but whenever I click on to connect is tries for 3 seconds then says "Connection Failed" I tried using the "Connect to server" using both IP and Name but no use, please HELP!! PS: I am new to Mac OS.
