[RESOLVED] VB.NET 2008 Remote Process Starting

Hello, the below code starts the correct process but the windows form never displays on the remote machine. How do I get the application to actually load.

Code:

---

    Private Sub RunRemoteProcess()
        Dim sCmd As String = "C:\Program Files\Internet Explorer\IEXPLORE.EXE " & txtData.Text.Trim

        ' add a reference to System.Management in Solution Explorer

        Dim wmi As ManagementClass
        Dim wmi_in, wmi_out As ManagementBaseObject
        Dim retValue As Integer

        Try
            wmi = New ManagementClass("\\" & HostName & "\root\cimv2:Win32_Process")
            ' get the parameters to the Create method
            wmi_in = wmi.GetMethodParameters("Create")
            ' fill in the command line plus any command-line arguments
            ' NOTE: the command can NOT be on a network resource!
            wmi_in("CommandLine") = sCmd
            ' do it!
            wmi_out = wmi.InvokeMethod("Create", wmi_in, Nothing)
            ' get the return code.  This not the return code of the
            ' application... it's a return code for the WMI method
            retValue = Convert.ToInt32(wmi_out("returnValue"))
            Select Case retValue
                Case 0
                    ' success!
                Case 2
                    Throw New ApplicationException("Access denied")
                Case 3
                    Throw New ApplicationException("Insufficient privilege")
                Case 8
                    Throw New ApplicationException("Unknown failure")
                Case 9
                    Throw New ApplicationException("Path not found")
                Case 21
                    Throw New ApplicationException("Invalid parameter")
                Case Else
                    Throw New ApplicationException("Unknown return code " & retValue)
            End Select
        Catch ex As Exception
            MsgBox(HostName & ": Can't create the process. " & ex.Message)
        End Try

make sure that you pass admin privileges (impersonation).

How would I go about doing the impersonation using the above code? I've seen other examples of wmi process creation but they don't seem to work properly. This example here at least is creating the process on the remote machine that I can see.

Hi.
A general example is:

Code:

---

Dim imp As New System.Management.ConnectionOptions
imp.Username = strUserName
imp.Password = strPassword
imp.Impersonation = Management.ImpersonationLevel.Impersonate
impt.Authentication = Management.AuthenticationLevel.PacketPrivacy

---

U use it after with ManagementScope

Haven't used impersonation for what u are doing so let us know if you can make it work.

I've come to the conclusion that it is impossible to run a process on the remote machine as the currently logged in user and have it display the new processes windows form on the users winstation. I have tried almost everything.

There is a simple answer to your problem. Under normal circumstances processes started remotely are prohibited from running interactively. The issue is explained in the following MSDN link.

Hi,

Thanks for that bit of info. It actually gave me the encouragement to start playing with this remote process execution again. I am basically trying to re-create what psexec does. So I'm assuming that I will have to have a service running on the localmachine and have the service's code create the Win32_Process.
