I've using robocopy to copy a 300GB files from one Windows Server to another Windows server over the WAN. However, I keep getting errors after copied several GBs and retrying from start. (for example, Error 317).
Are there any tools/scripts (prefer the built-in ones or "green" executables) which can resume copying if error occurs? I don't have physical access to the servers so sneakernet is not an option.

Robocopy supports resuming copying on error with the /Z switch. You can also specify number of retries and the amount of time between them with the /r and /w switches.
I personally think sneakernet is the best tool for copying huge files. Barring that, I've had success with using something like 7zip to split the file into smaller pieces, robocopy /Z them, and pasting them back together on the remote end.
