I've just had the same problem when transferring a large file (> 2 GB). The error appeared at different moment during the copy, but it always failed.
Disabling the anti-virus on the host machine didn't change the result.
I'm using Workstation 8, and the guest is running Windows 2008 R2 with VMware Tools version 8.8.0.471268 installed
Luckily, I was able to transfer the file by going through \\vmware-host\Shared Folders instead of going to the mapped drive letter.
