    Hi Team,

    I am using Invoke-vmscript to chnage the password of a computer via powershell. My script worked and changed the password as well but at the end i am getting the error mentioned below. Attaching the script aswell.

    Script:
    $VMcreds = Get-credential 
    $computer = "mycomputer"
    $user = "adminmycomputer"
    $code = @'
    $account = [ADSI]("WinNT://Computer/user")
    $password = Convertto-securestring "newpassword" -asplaintext -force
    $account.psbase.Invoke("setpassword", "$password")
    '@
    $code = $code -replace "computer" , "$computer"
    $script = $code -replace "user" ,"$username"
    Invoke-VMScript -VM $computer -ScriptType Powershell -ScriptText $script -GuestCredential $VMCreds

    Error: 
    Invoke-VMScript : Invoke-VMScript Failed to authenticate with the guest operating system using the supplied credentials.
    At line:204 char:13

    I suspect this is normal, you change the password, so the credentials you passed to Invoke-VMScript are not valid anymore.

    I normally use a scheduled task inside the Guest OS to make such changes.
    The scheduled task is scheduled a minute or so in the future, which gives the Invoke-VMScript ample time to return.
    As a test, you can after a couple of minutes, launch a new Ibvoke-VMScript with the new password to validate the password change succeeded.
