Using ROBOCOPY through Salt Master

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.

Salt seems to be connecting to the network resource with a computer account. A few possible solutions:

1. Try changing the Salt Service on the Client (if that's how salt is executing the commands) to run as a domain user.
2. Try using the salt file server
3. Implement this hacky workaround where a scheduled task is created - discussed in the github issue that seems related to your problem: https://github.com/saltstack/salt/issues/16340
