Powershell: How to use Invoke-WmiMethod to Beep a Remote Computer?

Question

I am trying to use the following code to make a beep on a remote computer through Powershell:

Invoke-WmiMethod -Path Win32_Process -Name Create -ArgumentList "[console]::beep(500,300)" -ComputerName "mycompname"

In addition I have used [System.Media.SystemSounds]::Beep.Play() in place of the console command. It doesn't give any error codes and outputs this:

__GENUS : 2 __CLASS : __PARAMETERS __SUPERCLASS : __DYNASTY : __PARAMETERS __RELPATH : __PROPERTY_COUNT : 2 __DERIVATION : {} __SERVER : __NAMESPACE : __PATH : ProcessId : ReturnValue : 9 PSComputerName :

I am running this command with elevated Powershell and I am an admin on the network. Using Invoke-Command DOES NOT work on my computer, so I am opting for Invoke-WmiMethod instead. The following code DOES actually work, so I don't understand why the beep one won't:

Invoke-WmiMethod -path Win32_Process -Name Create -ArgumentList "msg * 'hello'" -ComputerName "mycompname"

Final notes: I would like to be able to use Invoke-WmiMethod to do remote shutdown and taskkill, but those functions also do not work, only sending a message works. Any help would be greatly appreciated.

Answer 1

May be can you try this (modify username and password)

 $Username = 'labuser'
 $Password = 'labuser'
 $pass = ConvertTo-SecureString -AsPlainText $Password -Force
 $Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$pass


 Invoke-command –computername "mycompname" -credential $Cred –scriptblock {[console]::beep(500,300)}

Answer 2

TessellatingHeckler was right. I just needed to change the code so that the receiving computer knows that I am using powershell:

Invoke-WmiMethod -Path Win32_Process -Name Create -ArgumentList "powershell.exe [console]::beep(500,300)" -ComputerName "mycompname"

This also works for everything else:

 Invoke-WmiMethod -Path Win32_Process -Name Create -ArgumentList "powershell.exe shutdown -s" -ComputerName "mycompname"

Thanks!
