Reading remote registry with WMI returns no results

I am trying to read the HKEY_USERS hive of a remote machine with this Class

Code:

---

   
Imports System.Management
Imports System.Management.Instrumentation


Public Enum RegHive As UInteger
    HKEY_CLASSES_ROOT = &H80000000UI
    HKEY_CURRENT_USER = &H80000001UI
    HKEY_LOCAL_MACHINE = &H80000002UI
    HKEY_USERS = &H80000003UI
    HKEY_CURRENT_CONFIG = &H80000005UI
End Enum

Public Enum RegType
    REG_SZ = 1
    REG_EXPAND_SZ = 2
    REG_BINARY = 3
    REG_DWORD = 4
    REG_MULTI_SZ = 7
End Enum
Public Class RemoteRegistry
    Implements IDisposable
    Friend Shared mc As ManagementClass

    Public Sub New(target As String)
        Dim options As New ConnectionOptions()
        options.Impersonation = ImpersonationLevel.Impersonate
        options.EnablePrivileges = True
        If My.Settings.WMIUsingAlternateCredentials Then
            options.Username = My.Settings.WMIUserID
            options.Password = My.Settings.WMIPassword
        End If

        Dim myScope As New ManagementScope("\\" & target & "\root\default", options)
        Dim mypath As New ManagementPath("StdRegProv")
        mc = New ManagementClass(myScope, mypath, Nothing)
    End Sub

Public Function EnumKeys(hDefKey As RegHive, sSubKeyName As String) As String()

        Dim retval As String()
        Dim inParams As ManagementBaseObject = mc.GetMethodParameters("EnumKey")
        Dim outParams As ManagementBaseObject

        inParams("hDefKey") = hDefKey
        inParams("sSubKeyName") = sSubKeyName
        outParams = mc.InvokeMethod("EnumKey", inParams, Nothing)
        retval = DirectCast(outParams.Properties("sNames").Value, String())
       
        Return retval
    End Function
End Class

---

The value of sSubKeyName is the user's SID + "\" + Network (e.g. S-1-5-21-1606980848-2025429265-839522115-560021\Network). Now under that key are various subkeys containing mapped drive letters. But it never returns anything.

Strangely, if I use the OpenRemoteBaseKey method it works BUT I don't want to use that because using WMI lets me specify alternate credentials and OpenRemoteBaseKey doesn't

Any ideas?

G'd evening Ginolard,
I don't use to work with WMI, but i know that if you want to have access to the registry, all your machines must have running the remote registry service and the remote administration.
Having said that. WMI is not the only tool that can let you impersonate, the System.Security.Permissions class let you do just that.
G'd luck
