Hey Magneet,
Thanks for the quick response, I appreciate it. I had seen that blog, however I am specifically trying to use the method list in the link I posted....A picture I posted in my first post didn't get added....
Although the blog post you linked to would solve my problem, I was hoping not to use it as it would complicate the script I am trying to write.
Fortunate, or unfotunately, this was a scenario of as soon as I posted the question and asked for help I immediately solved it.
It turns out that although I had update the Connection server to the correct version to use the method machine_assignuser().....I hadn't update the PowerCLI module. After I did that update and restarted powercli/powershell it showed up
Thanks again for your reply. I appreciate it.
