Here is my configuration:
I have a brand new iMac i7! I also have a W2K3 server where I store video files including HD.

I have successfuly setup the connection to my Windows shares from my iMac. No problems, it's working fine expect the bandwith.

I am getting less than 15 MB/sec! I have everything on a gigabit lan with gigabit switch. If I replace the iMac with a laptop, then I have more than 400 MB/sec!

What's the problem? Could not find any reason to that. Any help?

Many thanks
