I run the command below and keep getting network path not found.  Why?

PS C:\Windows\System32\WindowsPowerShell\v1.0> $admin = [adsi]("WinNT://wdwzp3445/WilsonJP, user")

PS C:\Windows\System32\WindowsPowerShell\v1.0> $admin.psbase.invoke("SetPassword", "Test#1234")

Exception calling "Invoke" with "2" argument(s): "The network path was not found.

"

At line:1 char:1

+ $admin.psbase.invoke("SetPassword", "Test#1234")

$admin = [adsi]("WinNT://wdwzp3445/WilsonJP, user")
$admin.SetPassword('newpassword')

I tried your version and it still fails with the same error.

Running as admin and elevated?
