Can't remove Printer Port with Powershell

Question

Can any one explain what I'm doing wrong here?

PS C:\Windows\system32> Get-PrinterPort -Name "Xerox C9000"

Name ComputerName Description PortMonitor

---

Xerox C9000 Standard TCP/IP Port TCPMON.DLL

PS C:\Windows\system32> Remove-PrinterPort -Name "Xerox C9000"
Remove-PrinterPort : The specified server does not exist, or the server or printer name is invalid. Names may not contain ',' or '\'
characters.
At line:1 char:1

• Remove-PrinterPort -Name "Xerox C9000"
• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
• CategoryInfo : NotSpecified: (MSFT_TcpIpPrint...= "TCPMON.DLL"):ROOT/StandardCimv2/MSFT_PrinterPort) [Remove-PrinterPort], Cim
  Exception
• FullyQualifiedErrorId : HRESULT 0x80070709,Remove-PrinterPort

I can't get PowerShell to delete this port no mater what I do! I will delete manually just fine.

Hi,

Please try to run the below script as Administrator.

Restart-Service spooler  
Get-WmiObject -Query 'Select * from MSFT_PrinterPort where name Like "Xerox C9000"' -Namespace ROOT/StandardCimv2 | Remove-WmiObject

Hi,

Maybe delete the registry entry. Please try to run this as administrator.

$path = "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports"  
$name = "Xerox C9000"  
Remove-ItemProperty -Path $path -Name $name  
Restart-Service spooler  

If it doesn't work see if the port can be removed in the GUI.

1. Launch Control Panel\All Control Panel Items\Devices and Printers
2. Click on any of the listed printers.
3. Click “Printer server properties”.
4. Click the Ports tab.
5. Select the port and click “Delete port”.

Also try the prnport script

cscript $env:windir\System32\Printing_Admin_Scripts\en-US\prnport.vbs -d -r "Xerox C9000"

Stumbled upon this thread having the same problem, turns out the -ComputerName parameter is a must apparently.

Without:

Remove-PrinterPort -Name PRN*  
Remove-PrinterPort : Der angegebene Server ist nicht vorhanden, oder der Server- oder Druckername ist ungültig. Namen dürfen die Zeichen "," oder  
"\" nicht enthalten.  
In Zeile:1 Zeichen:1  
+ Remove-PrinterPort -Name PRN*  
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
    + CategoryInfo          : NotSpecified: (MSFT_TcpIpPrint...= "TCPMON.DLL"):ROOT/StandardCimv2/MSFT_PrinterPort) [Remove-PrinterPort], CimExcep  
   tion  
    + FullyQualifiedErrorId : HRESULT 0x80070709,Remove-PrinterPort  

But then..

Remove-PrinterPort -Name PRN* -ComputerName $env:computername  

.. works for me.

Funny thing is Remove-PrinterPort -Name PRN -WhatIf* ... shows that it should work without ComputerName but well.. it is what it is.

Sorry no luck...

Howdy! The point was to remove it with PowerShell so it could be automated. Still not sure why that command fails to work....
