I've got an ethernet cable connected between my iMac and a Windows computer. The aim of this was to connect them together so I can transfer files quickly. However the connection is very slow ~1.4MB/s . In OS X I am trying to connect to the windows computer using the shared section of the sidebar, i.e. with this button However when I enter the details here It doesn't connect, just remains as "Guest". Could this be due to the lack of a password on the windows computer so the password field is left blank. This is really annoying me as I thought it would be very easy to do but alas not. When I am connected as a "Guest" I can still transfer the files I need to as I have set the shared settings on the windows side accordingly. However I would like to gain root access to the windows machine and do so in a way that is fast(er). I have tried connecting via "Go - Connect to Server" and it runs at the same speed as it does via the Finder sidebar method. The connection speed due to limitations of the hardware on the windows side is 100Mbps which should be faster than 1.4 MB/s (11.2Mbps) even with latencies/inefficiencies inherent in the system. Is this really the fastest I can expect with this setup ? As I can transfer the information faster by going between an external USB hard drive. Any ideas what I am doing wrong?
