So my problem is that when using Windows to transfer a larger file > several gigabytes over SMB to my macs running 10.8.2, the file fails mid transfer. I have no issues whatsoever writing to a 3rd mac in the house that's still running 10.7.5. I've have NFS set up on my mac server and have tried using the Windows Client for NFS, and it works, but the performance is abysmal with the Windows Client (like 30MB/sec) - with my Macs and Linux the performance is 3x greater on NFS... I've also tried SFTP over Windows to see how that works, and there's similar poor performance. What's my best bet for quick and stable file transfers over the network from Windows to OS X 10.8.2? I've yet to try compiling the open source Samba and get that up and running. It's the only idea I have left.
