Joining a domain

I was creating a new virtual machine and decided to test the JoinDomainOrWorkgroup method of the Win32_ComputerSystem class

The syntax is relatively straight forward

$comp = Get-WmiObject Win32_ComputerSystem
$password = "Gu3ssWh4t"
$user = "Manticore\Richard"
$domain = "Manticore"
$comp.JoinDomainOrWorkgroup($domain, $password, $user, $null, 3)

It kept failing with a 1316 return code.  Couldn’t find a reference to that so eventually tried using Add-Computer.  That told me the computer account already existed.  OOOPS. Got the name wrong.  One quick rename later and we’re in business
