Can I find the path to a DCOM application executable with WMI or Powershell?

  • 772

I have installed (and registered) a DCOM application on a W2K8R2 machine, and its GUID can be found in the DCOM list shown by dcomcnfg.

I can also use Powershell to find a Win32_DCOMApplication or Win32_DCOMApplicationSetting object for its GUID:

PS C:\Windows\system32> Get-WMIObject Win32_DCOMApplicationSetting -Filter "AppID='{1CECFD4D-2CFB-4626-95C7-0266C26960FA
}'"


__GENUS                   : 2
__CLASS                   : Win32_DCOMApplicationSetting
__SUPERCLASS              : Win32_COMSetting
__DYNASTY                 : CIM_Setting
__RELPATH                 : Win32_DCOMApplicationSetting.AppID="{1CECFD4D-2CFB-4626-95C7-0266C26960FA}"
__PROPERTY_COUNT          : 12
__DERIVATION              : {Win32_COMSetting, CIM_Setting}
__SERVER                  : MYSRV
__NAMESPACE               : root\cimv2
__PATH                    : \\MYSRV\root\cimv2:Win32_DCOMApplicationSetting.AppID="{1CECFD4D-2CFB-4626-95C7-0266C269
                            60FA}"
AppID                     : {1CECFD4D-2CFB-4626-95C7-0266C26960FA}
AuthenticationLevel       :
Caption                   :
CustomSurrogate           :
Description               :
EnableAtStorageActivation : False
LocalService              :
RemoteServerName          :
RunAsUser                 :
ServiceParameters         :
SettingID                 :
UseSurrogate              : False

The output shows that there is a DCOM application entry for my GUID. However it does not show the path to the executable. Is there a way to retrieve the application executable's full path with WMI?

  1. Best Answer

    Using the Win32_ClassicCOMClassSetting class with Powershell

    Get-WMIObject Win32_ClassicCOMClassSetting -Filter "AppID='{1CECFD4D-2CFB-4626-95C7-0266C26960FA}'" | select -ExpandProperty InProcServer32

    or using WMIC

    wmic /namespace:\\root\cimv2 path Win32_ClassicCOMClassSetting WHERE AppID^="{1CECFD4D-2CFB-4626-95C7-0266C26960FA}" Get InProcServer32

    *this was tested on Windows 8.1 x64

    or using reg.exe

    reg QUERY HKCR\Wow6432Node\CLSID\{1CECFD4D-2CFB-4626-95C7-0266C26960FA}\Inprocserver32 /ve

  2. What happens when you search the registry for {1CECFD4D-2CFB-4626-95C7-0266C26960FA}?

    So the powershell component, this should get you started:

    $cred = Get-Credential domain\user
Enter-PSSession <name of computer> -Credential $cred
Set-Location HKCR:\Wow6432Node\CLSID\{1CECFD4D-2CFB-4626-95C7-0266C26960FA}\LocalServer32
