Just had a good laugh while reading Microsoft KB article 2258090:

When you try to copy a file that is larger than 2 GB over a Remote Desktop Services or a Terminal Services session through Clipboard Redirection (copy and paste) by using the RDP client 6.0 or a later version, the file is not copied. And, you do not receive an error message.

Wow, did you ever (attempt to) copy such a large file in your Remote Desktop Session?
