Using ROBOCOPY through Salt Master

Question

I have SLS files set up to copy things from a network folder to a local directory on a minion.

Looks a little like this: cmd-test: cmd.run: - name: 'ROBOCOPY \\\CygwinSource C:\CygwinSource /E'

and get the following output:

-------------------------------------------------------------------------------
   ROBOCOPY     ::     Robust File Copy for Windows

When I run the same thing locally in command line as 'ROBOCOPY \\\CygwinSource C:\CygwinSource /E' and it worked perfectly. I have no idea how to fix this 'use local user account' that Robocopy seems to give when using it through salt.

I also tried adding /MIR and /SEC which didnt't work.
