Not sure on port 902. It looks like it is connecting, but it is getting access denied, because it is using an account that the system doesn't know.
I'm feeling like an idiot, I don't see what I am suppose to do with that code, I can't even find where Powercli is 'installed' it's not in C:\Windows\System32\WindowsPowerShell\v1.0\Modules, or in 'my documents' either.
