Can't rename or delete image files on network share after a deployment task

After deploying an image using the Deployment Console, we can no longer rename or delete an image file located on a network share. The tech that created the job shows a read lock on the file on the network server. Even a week after the job has finished, we still can't rename or delete the file.

If we reboot the Acronis Snap Deploy Server, the file can be renamed or deleted. We haven't tried cycling the Acronis services on the server but I suspect that will work too. We're going to try it next time.

We have tried this with the same behavior on 2 different files servers. Currently the image files are stored on a Windows 2008 Storage Edition server.
