Running command on remote machine using WMI - vbscript

Question

I am trying to run following VB Script to run command on remote machine. I want this script to wait until command is executed completely.
Here is my code:
Function RemoteExecute(strServer, strUser, strPassword, strCommand,pro)
Dim objLocator , objWMIService
wbemImpersonationLevelImpersonate = 3
wbemAuthenticationLevelPktPrivacy = 6
RemoteExecute = -1
Set objLocator = CreateObject("WbemScripting.SWbemLocator")
On Error Resume Next
Set objWMIService = objLocator.ConnectServer(strServer,"root\cimv2", strUser,strPassword)
objWMIService.Security_.ImpersonationLevel = wbemImpersonationLevelImpersonate
objWMIService.Security_.AuthenticationLevel = wbemAuthenticationLevelPktPrivacy
If Err.Number <> 0 Then
WScript.Echo "Failed to connect to " &strServer, "Error # " & CStr(Err.Number) & " " & Err.Description & vbcrlf & _
"Please check if " & strServer & " is pingable from this client & credentials are correct"
Err.Clear
On Error GoTo 0
RemoteExecute = -1
Set objWMIService = nothing
Set objLocator = nothing
Exit function
end if
' Configure the process to show a window
Set objStartup = objWMIService.Get("Win32_ProcessStartup")
Set objConfig = objStartup.SpawnInstance_
objConfig.ShowWindow = SW_NORMAL
Set Process = objWMIService.Get("Win32_Process")
'Process.Create Syntax: '
' uint32 Create(
'[in] string CommandLine,
'[in] string CurrentDirectory,
'[in] Win32_ProcessStartup ProcessStartupInformation,
'[out] uint32 ProcessId
');
'Return code Description
'0 Successful Completion
'2 Access Denied
'3 Insufficient Privilege
'8 Unknown failure
'9 Path Not Found
'21 Invalid Parameter
intReturn = Process.Create(strCommand,NULL, objConfig, intProcessID)
If intReturn <> 0 Then
Wscript.Echo "Process could not be created." & _
vbNewLine & "Command line: " & strCommand & _
vbNewLine & "Return value: " & intReturn
Wscript.Quit
Else
Wscript.Echo "Process created." & _
vbNewLine & "Command line: " & strCommand & _
vbNewLine & "Process ID: " & intProcessID
RemoteExecute = intProcessID
End If
' Set objWMIService = GetObject("winmgmts:\\" & strServer & "\root\cimv2")
Set colMonitoredProcesses = objWMIService.ExecNotificationQuery_("SELECT *" +" FROM __InstanceDeletionEvent " +"WITHIN 5 WHERE TargetInstance ISA 'Win32_Process' " )
Do
Set objProcess = colMonitoredProcesses.NextEvent
Wscript.Echo objProcess.TargetInstance.Name
Wscript.Echo objProcess.TargetInstance.ExecutablePath
Wscript.Echo "1"
Wscript.Echo "proc:" & objProcess.TargetInstance.ProcessID
Wscript.Echo "int:" & intProcessID
If objProcess.TargetInstance.ProcessID = intProcessID Then
Wscript.Echo "I will end the monitoring of the process "
Wscript.Echo pro & objProcess.TargetInstance.Name
Exit Do
end If
Loop
Set objWMIService = nothing
Set objLocator = nothing
End Function
strServer = WScript.Arguments.Item(0)
strUser = WScript.Arguments.Item(1)
strPassword = WScript.Arguments.Item(2)
strCommand = WScript.Arguments.Item(3)
pro = WScript.Arguments.Item(4)
Call RemoteExecute(strServer, strUser, strPassword, strCommand,pro)
But problem I am facing is that, script run the process in background but not waiting for it.
Another point that I do not understand is, when try to echo following:
Wscript.Echo objProcess.TargetInstance.Name
Wscript.Echo objProcess.TargetInstance.ExecutablePath
Wscript.Echo "proc:" & objProcess.TargetInstance.ProcessID
it does no echo anything, whereas following are properly echoed with a nice pop up
Wscript.Echo "1"
Wscript.Echo "int:" & intProcessID
Can someone please resolve my problem, may be this problem is naive for someone, sorry I am naive here.
