Okay. I have been thinking about, and researching on the web and this "semaphore" error boils down to an indiscriminate time out.

It does not matter what configuration your machines are in. You can have XP, Vista, or 7 stand-alone or networked, and this problem can rear its ugly head. But, It does have something to do with the TCP window resizing feature.

This is the best tip I have found that works. What I would like you to do is follow the instructions to input this command:
netsh interface tcp set global autotuninglevel=disabled
with an elevated command window.
You may copy, and then paste this into the CMD window.

If you are unsure how to arrive at an elevated CMD prompt see:
Elevated Command Prompt

Then try to copy your file, and lets us know how it went.

The following link gives the best description concerning this error. Save it because in case you need to reverse the command :
Vista: TCP window scaling not compatible with some network hardware.
