Copying from Windows to a network share:
 
From a command prompt use the following command:  COPY <source file> <destination location> /B /Z
 
Be sure to use COPY, not XCOPY.  I’ve yet to get xcopy to restart.  The /Z will allow you to re-issue the command if it gets interrupted.  When you do this, you will be asked if you want to over write the existing file.  Say yes, and it will pick up where it left off.  I’ve copied several 4GB files in this manner and either dropped the VPN connection or interrupted the transfer using Ctrl-C.  Every file eventually completed successfully and produced the same CRC32 values as the original.  I like to use hashcalc for compute CRC32 values of the file before and after I copy it.  This verifies the integrity of the file.  Be sure to run hashcalc local to the file.
