I need to download a 10 GB VM file from a network drive. The problem is I periodically need to access a VPN connection which disconnects the network drive.

I am not able to resume the download after I disconnect from the VPN and re-access the network drive. I've tried 4 times.

I need the file as soon as possible for work. Will I need to wait until I finish working today to start the download and let it run over night?

I'm using Windows 7.

You should be able to use the command line tool Robocopy, which supports resuming transfers after network connections drop. It's now built into Windows 7. You can type robocopy /? to see all of the options. I suspect the section entitled Retry Options is most relevant to what you're doing. In particular, it might be worth it to set this parameter

/W:n :: Wait time between retries: default is 30 seconds.

If you are usually connecting to the VPN for periods of 10 or 20 minutes, it might be worth it to increase this retry wait time.

As an alternative, you may be able to set up the VPN connection so that you are still able to access local network resources. Some VPN setups allow this, and others don't.
