I had /have a Robocopy Script that was setup to copy files from a Workgroup computer to a Domain shared network Folder that was working for about 2 weeks but isn't now. Is there a Robocopy Script ...

If the powershell.exe process running the script is using next to 0% CPU, you're likely blocked on a command-line program waiting for input from the user.

The downside of this approach is that it means Robocopy doesn't behave consistently between different platforms, and scripts written to run on Vista systems won't make any sense on older machines.
