Start service on another machine without credentials
===

I've spent the better part of yesterday and this morning looking into this. I've come across Powershell, psexec, and WMI in my research. Nothing seems to work without having credentials of the second computer. 

All I want to do is simply stop a service, and then start a service on another machine in the domain where I work. Without credentials, I keep getting "Access Denied" errors. 

Does anyone know if this is possible without credentials? I'd prefer a Powershell suggestion, but I'll gladly listen to all suggestions.
