I have a MB running OS X Lion and several Windows Vista and Windows 7 computers in my house. I have enabled file sharing on the MB and on the Windows machines. All machines are set to the same workgroup. Accessing the Windows volumes from the MB works fine. I can see my MB through the Network places on all the windows machines. However, when I click on the MB, the windows machines are unable to connect. It gives me the option to 'diagnose' the problem. When I click that, it tells me to open TCP port 445 on the MB. I can access the MB shared volumes if I manually connect by opening 'run' and typing the IP address of the MB (i.e. \\192.168.0.190). Anyone have a solution for accessing the MB through Network Places rather than manually typing in the address? It's a matter of convenience, but the other users on my network aren't adept at technology and this would confuse them too much. Thanks in advance.
